Answer:
If one factor is (x-10) then the other factor is (x+2).
Step-by-step explanation:
We need to factorize the term x^2-8x-20
For factorization we need to break the middle term.
Middle term : -8x
Product of first and last term: -20x^2
Factors: -10x, +2x
Solving:
x^2-8x-20
x^2-10x+2x-20
x(x-10)+2(x-10)
(x-10)(x+2)
So, if one factor is (x-10) then other factor is (x+2)
