Following solutions to this equation?

Step-by-step explanation:

hello :

x²+6x+9 = 20

(x+3)²-20 = 0

(x+3)²-√20 = 0

(x+3-√20)(x+3+√20)=0

x+3-√20=0   or    x+3+√20=0

x = -3+√20   or x = -3-√20    answer  B

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
