Question 823282: Solve n^3 + 2n^2 - 15n = 0 by factoring. Show the factored form of the equation, and the resulting solutions.
Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
n^3 + 2n^2 - 15n = 0
n*(n^2 + 2n - 15 ) = 0
find factors of -15 which add up to +2
5 and -3
n*(n+5)*(n-3)=0
0, -5,3
