Question

Factor 100x^2-20xy+y^2

Answer 1

(10x-y)^2

Explanation:

1. The equation for a square of the difference problem like this is a^2-2ab+b^2=(a-b)^2
2. So now we have to find out a and b
3. b will be y, so now we need a
4. 100x=a^2, so that means a=10x
5. So now we plug in a and b into the solution which is (a-b)^2 so the answer will be (10x-y)^2

Answer 2

(10x-y)^2

(10x-y)(10x-y)
