Question

I am not sure how to do this diamond problem

Answer 1

Answer:

-10 and -10

Step-by-step explanation:

-10x-10=100

-10+-10=20

Answer 2

It looks like you are trying to factor a quadratic.  So you are looking for the numbers that when you multiply them, you get the top number (100), but when you add them you get the bottom number (-20).

Those two numbers are -10 and -10.

Hope that helps!
