Question

x2 + 9x + 18 = 0
i know both x's are a three just unsure of the negative signs

Answer 1

(x+6)(x+3)

Answer 2

Are you using the crisscross method or decomposition method?

Answer 3

sorry it is x=3 and x = 6 by the answer i just got i guess they are both positive

Answer 4

If you aren't already using the criss cross method, I'd recommend that one, as it is much easier.

Answer 5

x^2+9x+18 = 0
x^2+6x+3x+18=0
x(x+6) 3(x+6)
(x+6)(x+3)
