x^3+x^2+2x = x(x^2+x+2)
4x3+10x2+2x+5= (2x+5)(2x2+1)
(2x+3)(x+3)
(2x + 3)(x + 1)
Factor the numerator. x+1 is one of its factors (otherwise, it wouldn't be possible to simplify it). Then cancel the identical factors in the numerator and the denominator.
(2x + 1)(x + 3) are the factors.
(2x - 3)(x + 2)
2x3+2x2-12x take out GCF - 2x 2x(x2+x-6) factor - find factors of -6 that add up to 1 2x(x-2)(x+3)
9(2x + 5)
2(x + 13)
I assume you mean factors for 4x2+10x+6.(2x+3)(2x+2).
Factors are (x + 4)(x - 2) so x = -4 or 2
2x^2 + 13 doesn't have rational factors.
