(x + 10)(x + 4)
(x + 4)(x - 3)(x - 2)
As written, that equals 325 - 14x which is in its simplest form.
(2x+3)(2x+4)
(4x + 1)(2x + 3)
x2 - 14x + 49(x - 7) (x - 7)
x2 - 14x + 45 = (x - 5)(x - 9).
8x^2 + 14x + 3 factors to (4x + 1)(2x + 3)
21x3-35x2+14x = 7x(3x2-5x+2)
(x + 10)(x + 4)
(x - 2)(5x + 24)
-x2+14x=49
