(3 - i)(3 + i)
x(x + 3)(x - 4)
2y(y + 3)(y - 7)
(a - 2)(a^2 + 6)
Without that other number, all you've got is zero.
Factor out the GCF and get X(X2-X+1).
xcubed-1 Answer::(X-1)(Xsquared+X+1) when you factor xcubed minus a number its the same thing as x cubed minus y cubed and x cubed minus y cubed factors to:: (x-y)(xsquared+xy+y squared) the first factor, (x-y), is the cubed root of the first and the cubed root of the second, so in the answer i have (x-1), which is x cubed minus one cubed :) the second factor, (xsquared+xy+ysquared), you take the first number squared, Xsquared, then the first and second one multiplied together, XY, and then the second number squared, Ysquared, so in the answer i have (xsquared+x+1), which is x squared, then x times 1 which is just x, and positive 1, which is negative 1 squared :) x^3 - 1
(2x3 - x2) = x2 (2x - 1)
The expression does not have rational factors.
(x - 14)(x + 14)
(x + 6)(x - 6)
