I need help with this

(-3 , 0)

Step-by-step explanation:

The x-intercept is the point on which lies on the x-axis, so when the y is equal to 0.

They y-value can be seen as gaining 16 whole numbers every time the x gains 3.

1. Add intervals of +16 to the y-value (from -32) and intervals of +3 to the x-value (from -9) until the y-value equals 0.

Show:

(-9+3 , -32+16) = (-6 , -16)

(-6+3 , -16+16) = (-3 , 0)

The y-value in the end, is 0 with a x-value of -3.

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
