Point c is on line segment \overline{bd}
bd
. given bd=5x, bd=5x, bc=4x, bc=4x, and cd=4,cd=4, determine the numerical length of \overline{bd}.
bd
.

the answer will be b x² +x-1

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
