Would be great if someone explained this

A. 2.

A radical is an expression which implies the use of a root.

There are three components of a radical expression:

(i) The root "√".

(ii) The radicand √"a".

(iii) The degree or index of the radical , when index of the radical is not shown then it understood to be a index of 2.

The index is the number used to indicate the degree of the root.

For the example , 10 is the radican and the index is not shown so it understood is 2.

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
