x times x times x
x3-343
Since x3 is a factor of x5, it is automatically the GCF.
Greatest common factor of x4 and x3 is x3.
The greatest common factor of 1-x3 is 1, dummy.
y5(x3 - 8)
X3 X(X2) X2(X) and, X * X * X
x3+27y3 = (x+3y) · (x2-3xy+9y2)
Choose the lowest of the exponents. The GCF of x3 and x5 is x3
x2(x - 8)
x3 + 8 = x3 + 23 = (x + 2)[x2 - (x)(2) + 22] = (x + 2) (x2 - 2x + 4)
x3 + 8 = x3 + 23 = (x + 2)(x2 + 2x + 22) = (x + 2)(x2 + 2x + 4)
x3 + 2x2 + 5x + 4 = (x + 1)(x2 + x + 4)
