Keisha is making a table summarizing her notes about the different types of investigation. She places an X into the table to show which steps are included in a descriptive investigation. Part of the table is shown. Where should Keisha place an X?

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
