Answer:

(x-1) and (x+8).

Step-by-step explanation:

The given expression is :

[tex]x^2+7x-8[/tex]

We need to find the factors of this expression.

Product of two numbers = 8 and -1 = -8

Sum of two numbers = 8 and -1 = 7

So,

[tex]x^2+7x-8=x^2+8x-x-8\\\\=x(x+8)-1(x+8)\\\\=(x-1)(x+8)[/tex]

So, the factors of this expression are (x-1) and (x+8).
