Introduction

In mathematics, a quadratic function is a polynomial function of degree two, which means the highest power of the variable is two. The standard form of a quadratic function is given by the equation f(x)=ax2+bx+cf(x) = ax^2 + bx + c, where aa, bb, and cc are constants. However, there is another form of a quadratic function called the vertex form, which is given by the equation f(x)=a(x−h)2+kf(x) = a(x - h)^2 + k. In this article, we will learn how to convert the standard form of a quadratic function to its vertex form.

The Standard Form of a Quadratic Function

The standard form of a quadratic function is given by the equation f(x)=ax2+bx+cf(x) = ax^2 + bx + c. This form is also known as the general form of a quadratic function. The coefficients aa, bb, and cc can be any real numbers, and the variable xx can be any real number.

The Vertex Form of a Quadratic Function

The vertex form of a quadratic function is given by the equation f(x)=a(x−h)2+kf(x) = a(x - h)^2 + k. This form is also known as the vertex form of a quadratic function. The vertex form is a more convenient form to work with, especially when graphing quadratic functions.

Converting the Standard Form to Vertex Form

To convert the standard form of a quadratic function to its vertex form, we need to complete the square. The process of completing the square involves rewriting the quadratic expression in a perfect square trinomial form.

Step 1: Factor out the Coefficient of x2x^2

The first step in completing the square is to factor out the coefficient of x2x^2. This will make it easier to complete the square.

f(x) = 2x^2 + 16x + 35

Step 2: Add and Subtract the Square of Half the Coefficient of xx

The next step is to add and subtract the square of half the coefficient of xx. This will help us to create a perfect square trinomial.

f(x) = 2(x^2 + 8x) + 35

Step 3: Add and Subtract the Square of Half the Coefficient of xx

Now, we need to add and subtract the square of half the coefficient of xx. Half of the coefficient of xx is 4, and the square of 4 is 16.

f(x) = 2(x^2 + 8x + 16) + 35 - 32

Step 4: Simplify the Expression

Now, we can simplify the expression by combining like terms.

f(x) = 2(x + 4)^2 + 3

Step 5: Write the Equation in Vertex Form

Now that we have completed the square, we can write the equation in vertex form.

f(x) = 2(x - (-4))^2 + 3

Step 6: Simplify the Equation

Finally, we can simplify the equation by combining like terms.

f(x) = 2(x + 4)^2 + 3

Conclusion

In this article, we learned how to convert the standard form of a quadratic function to its vertex form. We used the process of completing the square to rewrite the quadratic expression in a perfect square trinomial form. We also learned how to simplify the expression and write the equation in vertex form. The vertex form of a quadratic function is a more convenient form to work with, especially when graphing quadratic functions.

Example

Let's consider an example to illustrate the process of converting the standard form to vertex form.

Suppose we have the quadratic function f(x)=3x2+12x+15f(x) = 3x^2 + 12x + 15. We can convert this function to vertex form by completing the square.

Step 1: Factor out the Coefficient of x2x^2

The first step is to factor out the coefficient of x2x^2.

f(x) = 3(x^2 + 4x) + 15

Step 2: Add and Subtract the Square of Half the Coefficient of xx

The next step is to add and subtract the square of half the coefficient of xx. Half of the coefficient of xx is 2, and the square of 2 is 4.

f(x) = 3(x^2 + 4x + 4) + 15 - 12

Step 3: Simplify the Expression

Now, we can simplify the expression by combining like terms.

f(x) = 3(x + 2)^2 + 3

Step 4: Write the Equation in Vertex Form

Now that we have completed the square, we can write the equation in vertex form.

f(x) = 3(x - (-2))^2 + 3

Step 5: Simplify the Equation

Finally, we can simplify the equation by combining like terms.

f(x) = 3(x + 2)^2 + 3
