Question 980171: Please help me solve this equation.
2(3n(n-2)) = 3(2n(n-1)+12

Answer by ikleyn(52778) (Show Source): You can put this solution on YOUR website!

2(3n(n-2)) = 3(2n(n-1) + 12,

2*(3n^2 - 6n) = 3*(2n^2 -2n) + 12,

6n^2 - 12n = 6n^2 - 6n + 12.

-6n = 12.

n = -2.

Check: Left side is 2*3*(-2)*(-4) = 48. Right side is 3*2*(-2)*(-3) + 12 = 36 + 12 = 48. Both sides are the same.

Answer. The solution is n = -2.
