Question

Super confused definitely need help on this

Answer 1

Explanation:

x^2 + 8x - 5x - 40

x^2 + 3x - 40

Answer 2

`(x-5)(x+8)=x^2+3x-40`

Explanation:

So we have the expression:

`(x-5)(x+8)`

To multiply, distribute the left to the terms on the right:

`=(x-5)(x)+(x-5)(8)`

Distribute:

`=(x^2-5x)+(8x-40)`

Combine like terms:

`=(x^2)+(-5x+8x)+(-40)`

Simplify:

`=x^2+3x-40`

Therefore:

`(x-5)(x+8)=x^2+3x-40`
