(x - 1)(x - 1)(x - 1) - (x + 1)(x + 1)(x + 1)
x(x + 9)(x + 1)
If that's 5x2, it factors to (x + 5)(x2 + 1)
x is approximately 0.7549
(x - 1)(2x^2-1)
(x - 1)(x - 1)(x - 1) - (x + 1)(x + 1)(x + 1)
x3 + x = x2(x + 1)
x(x^2 + 1)
x(x + 9)(x + 1)
x(x + 9)(x + 1)
If that's 5x2, it factors to (x + 5)(x2 + 1)
x3 + x = x(x2+1)
x is approximately 0.7549
(x - 1)(2x^2-1)
That becomes x^2 - x + 1
x(x4+x3+x2+x+1)
(x + y)(x + y)(x + y)
