SOLUTION: solve the following quadratic equation by factoring 15x^3-4x^2-4x=0

Question 78619: solve the following quadratic equation by factoring
15x^3-4x^2-4x=0
Answer by chitra(359) (Show Source): You can put this solution on YOUR website!
The given expression is:

==> or 3x - 2 = 0

==> x(5x + 2) = 0 or (3x - 2) = 0

==> x = 0 or (5x + 2) = 0 or 3x = 2

==> x = 0 or 5x = -2 or x = 2/3

==> x = 0 or x = -5/2 or x = 2/3

Since the given polynomial is a cubic polynomial we get 3 roots and the roots are:

x = 0, x = -5/2, x = 2/3

Hence, the solution.
