Introduction

In algebra, synthetic division is a method used to divide polynomials by linear factors. It is a powerful tool that can be used to simplify fractions and rewrite them in a more manageable form. In this article, we will explore how to use synthetic division to rewrite a fraction in the form q(x)+r(x)d(x)q(x)+\frac{r(x)}{d(x)}, where d(x)d(x) is the denominator of the original fraction, q(x)q(x) is the quotient, and r(x)r(x) is the remainder.

What is Synthetic Division?

Synthetic division is a method of dividing polynomials by linear factors. It is a shortcut method that allows us to divide polynomials without having to use long division. The method involves using a single number, called the divisor, to divide a polynomial. The divisor is usually a linear factor, such as xax-a, where aa is a constant.

How to Perform Synthetic Division

To perform synthetic division, we need to follow these steps:

  1. Write down the coefficients of the polynomial in a row, with the constant term on the right.
  2. Write down the divisor, which is usually a linear factor.
  3. Bring down the first coefficient.
  4. Multiply the divisor by the first coefficient and write the result below the second coefficient.
  5. Add the second coefficient and the result from step 4.
  6. Repeat steps 4 and 5 until you reach the last coefficient.
  7. The final result is the quotient and the remainder.

Example 1: Dividing a Polynomial by a Linear Factor

Let's say we want to divide the polynomial x2+3x+2x^2+3x+2 by the linear factor x2x-2. We can use synthetic division to find the quotient and the remainder.

We start by bringing down the first coefficient, which is 1. Then, we multiply the divisor, x2x-2, by the first coefficient, which gives us 2x22x-2. We write the result below the second coefficient, which is 3.

Next, we add the second coefficient and the result from step 4, which gives us 3+2=53+2=5. We write the result below the third coefficient, which is 2.

We repeat the process until we reach the last coefficient. The final result is the quotient and the remainder.

The quotient is x+5x+5 and the remainder is 4.

Rewriting a Fraction using Synthetic Division

Now that we have learned how to perform synthetic division, let's see how we can use it to rewrite a fraction in the form q(x)+r(x)d(x)q(x)+\frac{r(x)}{d(x)}.

Let's say we have the fraction x2+3x+2x2\frac{x^2+3x+2}{x-2}. We can use synthetic division to rewrite the fraction in the form q(x)+r(x)d(x)q(x)+\frac{r(x)}{d(x)}.

We start by dividing the numerator, x2+3x+2x^2+3x+2, by the denominator, x2x-2. We can use synthetic division to find the quotient and the remainder.

2 6 4

The quotient is x+5x+5 and the remainder is 4.

Therefore, we can rewrite the fraction as x+5+4x2x+5+\frac{4}{x-2}.

Q: What is the quotient in synthetic division?

A: The quotient is the result of dividing a polynomial by a linear factor. It is the polynomial that remains after the division.

Q: What is the remainder in synthetic division?

A: The remainder is the amount left over after dividing a polynomial by a linear factor. It is the difference between the dividend and the product of the divisor and the quotient.

Q: Can I use synthetic division to divide polynomials by quadratic factors?

A: No, synthetic division can only be used to divide polynomials by linear factors. It cannot be used to divide polynomials by quadratic factors or higher-degree factors.

Q: How do I know if a polynomial can be divided by a linear factor?

A: A polynomial can be divided by a linear factor if the remainder is zero. If the remainder is not zero, then the polynomial cannot be divided by the linear factor.

Q: Can I use synthetic division to find the roots of a polynomial?

A: Yes, synthetic division can be used to find the roots of a polynomial. If the remainder is zero, then the divisor is a root of the polynomial.

Q: How do I use synthetic division to rewrite a fraction?

A: To use synthetic division to rewrite a fraction, you need to divide the numerator by the denominator. The quotient will be the new numerator, and the remainder will be the new denominator.

Q: Can I use synthetic division to simplify complex fractions?

A: Yes, synthetic division can be used to simplify complex fractions. You need to divide the numerator and denominator separately, and then combine the results.

Q: How do I know if a fraction can be simplified using synthetic division?

A: A fraction can be simplified using synthetic division if the denominator is a linear factor. If the denominator is a quadratic factor or higher-degree factor, then synthetic division cannot be used.

Q: Can I use synthetic division to solve equations?

A: Yes, synthetic division can be used to solve equations. You need to divide the polynomial by the linear factor, and then set the remainder equal to zero.

Q: How do I use synthetic division to solve a system of equations?
