a) x^2 + 3x - 28 = 0

(x+7)(x-4)

d)x^2 + 8x + 16 = 0

(x+4)(x+4)

f)9x^2 - 4 = 0

i)8k^2 - 3k = 0

k)x^2/6 - x + 4/3 = 0

did i do a and d right? Can you show me how to solve the rest?

**PsyDAG**, Wednesday, June 1, 2011 at 3:10ama) If (x+7)(x-4) = 0 then x = -7 or 4.

d) x = -4

Yes, you did a and d right, but carry it out all the way.

f) (3x-2)(3x+2) = 0

I don't have the time to deal with the remaining problems.
