Question

Select the correct answer.What is the simplified form of this expression?(-3x²+x+5)-(4x² – 2x)OA X-X+5OB. +3x-11OC 7x+3x-5OD. -7x+3x+5

Answer 1

Given: The expression below

$(-3x^2+x+5)-(4x^2-2x)$

To Determine: The simplified form of the given expression

Solution

Let us expand the parenthesis

$\begin{gathered} (-3x^2+x+5)-(4x^2-2x) \\ =-3x^2+x+5-4x^2+2x \end{gathered}$

Collect like terms

$\begin{gathered} =-3x^2-4x^2+x+2x+5 \\ =-7x^2+3x+5 \end{gathered}$

Hence, the simplified form of the given expression is

-7x² + 3x + 5
