Answer 1

Note: Your answer choices remain a little unclear. But, I have solved the concept and solution, so you can easily figure it out.

Answer:

`\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4`

Explanation:

Given the expression

`\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)`

solving the expression

`=-7x^0+5x^2-x+6-\left(-8x^2+x+3\right)`

apply the rule:
`a^0=1,\:a\\e \:0`

`=-7+5x^2-x+6-\left(-8x^2+x+3\right)`

`=-7+5x^2-x+6+8x^2-x-3`

simplify

`=13x^2-2x-4`

Therefore, the simplified form is:

`\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4`
