10x + 5 unless you know what x & y are * * * * * Perhaps this answer will be of help: x3 + x2 + 5x + 5 = (x + 1)(x2 + 5). If you are willing to go to complex roots, then, x3 + x2 + 5x + 5 = (x + 1)(x2 + 5). = (x + 1)(x + i√5)(x - i√5); in which case, x = -1 or ±i√5.
x(x2+5x+6)

x2 + 5x - 120 can not be factored.
(3x - 5x) + (x2 - 6x2) = -2x -5x2 = -x(2 + 5x)
2x + 5x = 7x
x2 - 5x + 6 = (x - 2)(x - 3)
x2 - 5x = 0x (x - 5) = 0x = 0andx = 5
x2-5x-50 = (x+5)(x-10) when factored
x2 + 5x + 6 = (x + 2)(x + 3)
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
x2+5x-14 = (x+7)(x-2) when factored
When factored it is: (x-9)(x+4)
5x+x >100
