Factor completely and then place the factors in the proper location on the grid.

a2 - a - 20

For this case we have the following polynomial:

We must factor the polynomial.

To do this we look for two numbers that are added equal to -1 and multiplied equal to -20.

Factoring we have:

The factored expression is given by:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

no he doesnt because "-16' is negatiive
