Replace ∗ with a monomial so that the expression can be rewritten as a square of a sum or a difference: 0.01b^2 + ∗ + 100c^2

Replace ∗ with a monomial so that the expression can be rewritten as a square of a sum or a difference:

25a^2 + * + 1/4b^2

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

n

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
