Solve for x:
3 x^2+20 x+12 = 0
The left hand side factors into a product with two terms:
(x+6) (3 x+2) = 0
Split into two equations:
x+6 = 0 or 3 x+2 = 0
Subtract 6 from both sides:
x = -6 or 3 x+2 = 0
Subtract 2 from both sides:
x = -6 or 3 x = -2
Divide both sides by 3:
Answer: | x = -6 or x = -2/3
