(x + y)(x + y)(x + y)
Factor out the GCF and get X(X2-X+1).
x(x2+5x+6)
x(x^2 + 2x + 9)
x(x + 9)(x + 1)
x(x + 9)(x + 1)
Since the problem has 4 terms, first you factor x cubed plus 9x squared, then you factor 2x plus 18. So when you factor the first two term, you would get x sqaured (x plus 9). Then when you factor the last two terms and you get 2 (x plus 9). Ypure final answer would be (x squared plus 2)(x plus 9)
x(x - 19)(x - 1)
2x(x^2+x-6)
2(x^2 + 2)(x + 3)
2(x + 3)(x^2 + 4)
x(x4+x3+x2+x+1)
