(x - 5)(x + 4)
(x+4)(x-7)
(x + 2)(x - 4)
4
x^(3) - x^(2) - 12x 'x' is a common fractor ' tsker it out. Hence x(x^(2) - x - 12) Factor inside the brackets / x(x - 4(x + 3) Done!!!!!
x = ? 42 = x squared minus x
2
1/x4
3x2 - 11x - 4 = (x-4)(3 x + 1)
(x+2)(x−4)
(x-1)(x-4)
It is the difference of squares. (x-4) and (x+4) <--- answer
