3. Which equation is equivalent to y = x - 6? A. 2x+3y=-6
B. 3x-2y=6
C. 3x-2y=12
D. 2x-3y=18

there are infinitely many solutions.

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

you,
