Introduction

In algebra, polynomial expressions are a fundamental concept that plays a crucial role in solving various mathematical problems. When dealing with polynomial expressions, it's essential to apply the rules of exponents and simplify the expressions to make them more manageable. In this article, we will focus on simplifying a given polynomial expression by applying the rules of exponents and recalling past experiences with linear and quadratic expressions.

Understanding Polynomial Expressions

A polynomial expression is a mathematical expression that consists of variables and coefficients combined using addition, subtraction, and multiplication. The variables in a polynomial expression can be raised to various powers, and the coefficients can be any real number. Polynomial expressions can be classified into different types, including linear, quadratic, cubic, and so on, based on the highest power of the variable.

Simplifying the Given Polynomial Expression

The given polynomial expression is:

(2t2−3t+1)−(4t2−t−5)\left(2 t^2-3 t+1\right)-\left(4 t^2-t-5\right)

To simplify this expression, we need to apply the rules of exponents and combine like terms. The first step is to distribute the negative sign to the terms inside the second set of parentheses.

(2t2−3t+1)−(4t2−t−5)\left(2 t^2-3 t+1\right)-\left(4 t^2-t-5\right)

=2t2−3t+1−4t2+t+5= 2 t^2 - 3 t + 1 - 4 t^2 + t + 5

Now, we can combine like terms by adding or subtracting the coefficients of the same variables.

=2t2−4t2−3t+t+1+5= 2 t^2 - 4 t^2 - 3 t + t + 1 + 5

=−2t2−2t+6= -2 t^2 - 2 t + 6

Applying the Rules of Exponents

In the simplified expression, we have a term with a negative exponent, −2t2-2 t^2. To apply the rules of exponents, we need to recall that a negative exponent indicates that the variable is raised to a power of -1. In this case, we can rewrite the term as:

−2t2=−2t−2-2 t^2 = -2 t^{-2}

However, in this expression, we don't have any negative exponents, so we don't need to apply this rule.

Recalling Past Experiences with Linear and Quadratic Expressions

When simplifying polynomial expressions, it's essential to recall past experiences with linear and quadratic expressions. Linear expressions are of the form ax+bax + b, where aa and bb are constants, and quadratic expressions are of the form ax2+bx+cax^2 + bx + c, where aa, bb, and cc are constants. By recalling these expressions, we can apply the rules of exponents and simplify the given polynomial expression.

Using the Canvas Equation

The Canvas Equation is a tool that can be used to simplify polynomial expressions. It allows us to enter the expression and apply various operations, such as distributing the negative sign and combining like terms. By using the Canvas Equation, we can simplify the given polynomial expression and obtain the final result.

Conclusion

In conclusion, simplifying polynomial expressions is a crucial skill in algebra that requires applying the rules of exponents and recalling past experiences with linear and quadratic expressions. By following the steps outlined in this article, we can simplify the given polynomial expression and obtain the final result. The Canvas Equation is a useful tool that can be used to simplify polynomial expressions and make them more manageable.

Final Answer

The final answer to the given polynomial expression is:

−2t2−2t+6-2 t^2 - 2 t + 6
