ax^2 + bx + c = 0 is the quadratic equation. The coefficient of x^2 which is**a**can be positive or negative.

-2x^2 + x + 3 = 2x^2 - x - 3 = 0, but in case you have this -2x^2 + x + 3 = 0, using quadratic formula, a = -2. But if you choose 2x^2 - x - 3 = 0, then a = 2. - Oct 8th 2009, 04:56 AMstapel
