1. love_math

(a-b)^2=a^2-2ab+b^2

2. Compassionate

You first multiple inside parenthesis. 2 * 3x 2 * -5

3. Compassionate

For the other one use the FOIL method: First, Inner, outer, Last.

4. love_math

it is square not 2

5. bombshellbri

@love_math is right. it is squared.

6. Compassionate

I'm aware.

7. bombshellbri

why;d you erase your first comment?

8. Compassionate

9x^2 - 25 x^2 - x - 12

9. bombshellbri

a. 9x2 – 30x + 25 was the answer

10. Compassionate

No it wasn't. \[(3x - 5)^2\] \[3x^2 - 25\] This polynomial is not factorable with real numbers. Your test is messed up. So maybe it wants: \[9x^2 - 25\] Again, this polynomial isn't factorable with real numbers. Your test is wrong.

11. bombshellbri

sure.
