The GCF is 15x^2y^2
15x squared plus eleven
9x squared-15x squared = -6
x + 10
x + 5
The GCF is 15x^2y^2
5x^3(3x + 2)
15x squared plus eleven
9x squared-15x squared = -6
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
x + 10
x + 5
3(x + 4)(x + 1)
-15x2+5x=-5x(3x-1)
5x(3x + 1)
3(2x - 1)(x - 2)
x + 5; provided, of course, that x ≠ -10.
