Question

Type the correct answer in each box.Consider the expressions shown below.

Answer 1

The first expression is

`(3x^2-6x+11)-(10x^2-4x+6)`

First, we use the distributive property

`3x^2-6x+11-10x^2+4x-6`

Then, we combine like terms

`-7x^2-2x+5`

The first answer is A.

The second expression is

`\begin{gathered} (-3x^2-5x-3)-(-10x^2-7x+2) \\ -3x^2-5x-3+10x^2+7x-2 \\ 7x^2+2x-5 \end{gathered}`

The second answer is C.

The third expression is

`\begin{gathered} (12x^2+6x-5)-(5x^2+8x-12) \\ 12x^2+6x-5-5x^2-8x+12 \\ 7x^2-2x+7 \end{gathered}`

The third answer is B.
