Answer:
(x-7)(x-10)
Explanation:
x^2 - 17x + 70
This is in a form where you can factor by opening two parentheses of
x's
(x )(x )
You need 2 numbers that multiply to 70 and add to get to -17
7 and 10 are the candidates.
If you make 7 and 10 both negative, they shall add up to -17 since a negative and a negative indicates addition. Also, -7 multiplied by -10 cancels the negative to get a positive 70.
