12n3+12n2−12n3+18n

Answer 1

Hi, this question is asking you to cancel out like terms. It looks scary but you can see two terms that cancel each other out right away: 12n3 - 12n3

12n3 + 12n2 - 12n3 +18n

Let's rewrite the equation.

12n2 + 18n

Factor out like factors for 12 and 18 (factors: 2, 3, 6)

Answer: 6n(2n +3)
