5x(x+3)
(x - 1)(x - 14)
-3(x - 3)(x + 1)(x + 1)
The GCF is 15x^2y^2
use the quadratic formula since there isn't a factor of 60 that when added together equals 19 The above answer is wrong because 4 and 15 are such numbers. x2 + 19x + 60 = x2 + 4x + 15x + 60 = x(x + 4) + 15(x + 4) = (x + 4)(x + 15)
You can't factor it
9xy2 - 24xy + 15x
3x
5x
5x(x+3)
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
(x + 7)(x + 8)
3x(56x2-15x+1)
3(x + 4)(x + 1)
That doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (15 plus or minus the square root of -3) divided by 2x = 7.5 + 0.8660254ix = -0.8660254iwhere i is the square root of negative one.
(x-11)(x-4)
-15x2+5x=-5x(3x-1)
