Answer:
Explanation:
x^2-12x+36
You need to find 2 numbers that multiply to equal 36 and add to get you -12.
1,2,3,4,6,6,9,12,18,36
The possible numbers that would work would be 6 and 6. Since 6 x 6 is 36 but adds up to get +12, we need to make it so that they add together to get -12.
In that case we get, (x-6)(x-6), or (x-6)^2.
To check if it is correct you can use the FOIL method.
