21x3-35x2+14x = 7x(3x2-5x+2)
8x^2 + 14x + 3 factors to (4x + 1)(2x + 3)
2(x - 3)(x - 4)
(3x - 2)(2x + 6) or 2(3x - 2)(x + 3)
5x^2 + 14x - 3x^2 - 9 = 2x^2 + 14x - 9
(14x^3 - 10x^2) = 2x^2(7x - 5) 63x - 45 = 9(7x - 5) 14x^3 - 10x^2 + 63x - 45 = (2x^2 + 9)(7x - 5)
21x3-35x2+14x = 7x(3x2-5x+2)
(x - 2)(5x + 24)
8x^2 + 14x + 3 factors to (4x + 1)(2x + 3)
3x^2 -14x +15 = (3x-5)(x-3)
2(x - 3)(x - 4)
-x2+14x=49
-x2-14x-45 = -(x2+14x+45) delta = 142-4*1*45=16 so x2+14x+45=(x-(-14+4)/2) (x-(-14-4)/2) = (x+5)(x+9) so -x2-14x-45 = -(x+5)(x+9)
(3x - 2)(2x + 6) or 2(3x - 2)(x + 3)
(x2 + 14x + 49) = (x + 7)2
14x(x + 2)
Start by dividing by 2: 2(3x2 + 7x - 6) = 2(3x - 2)(x + 3)
