[ Ax2 + Bx + C ] is one example.
the difference between the two is that in quadratic u find the factors of the last term that when u add/subtract u get the answer of the middle term. while the general quadratic trinomial u find the factors of both first term and last term and proceed to trial and error.

square
It is a quadratic expression and can be factored into: (3x+1)(x+2)
-- If the last term of the trinomial ... the one that's just a number with no 'x' ... is positive, then both factors have the same sign as the middle term of the trinomial. -- If the last term is negative, then the factors have different signs. If this was never pointed out in class, well, it should have been.
(4x - 3)(2x + 3)
(7x + 8)(7x - 9)
(3x + 1)(x - 4)
(4x - 3)(2x + 3)
(x + 9)(x -1)
(10x + 1)(x + 10)
If that's +32, the answer is (x - 4)(5x - 8)
9
If that's +72y, the answer is 2y(x - 9)(3x - 4)
The factors of 6x2+7x-5 are (3x+5) and (2x-1).
3x2-7x+4 = (3x-4)(x-1) when factored
x2 + 8x - 9 = (x + 9)(x - 1)
