Question

(6x^3 + 18x^2) - 3x^2 =

Answer 1

you want this simplified right?

Answer 2

if so, all your doing is combining like forms...
here are the steps of doing so...
(6x^3 + 18x^2) - 3x^2 =

Remove parentheses...6x^3 + 18x^2 - 3x^2 =
now if you look you will see that 18x^2 and 3x^2 are like terms sooo you combine to get 15x^2

that leaves you with it simplified at 6x^3+15x^2

Hope this helps!

Answer 3

=6x^3 + 18x^2 - 3x^2
=6x^3+15x^2
= 3x^2 (2x+5)

Answer 4

I would just combine like terms. first the 18x^2 -3x^2 for which you get 15x^2. since you cant do anything with the 6x^3, because the exponets are different then you have 6x^3+15x^2 :D
