Want to see your attempts to see what the problem is. I will do one two ways as an example:
10. (x-2)(x+4)
This can be written as
x(x+4) -2 (x+4)
= x^2 + 4x - 2x - 8
= x^2 + 2x - 8
OR
use FOIL (first outer inner last)
x^2- 4x - 2x - 8 which is a similar ressult
Pls help me!!
I need the answers to these few questions I just cant figure them out and I have to turn them in asap
Simplify each polynomial. Write each in standard form.
HINT: Watch for the operation! Add? Subtract? Or Multiply?
8. 4m(2m+9m^2-6)
9. q(11+8q-2q^2 )
10. (x-2)(x+4)
11. (6g+7)(3g-8)
12. (x-1)^2
13. (4y+2)^2
