WebStep 1 (Alternate Solution) Show that ( x − 3) ( x 2 + 3 x + 9) matches the correct pattern for the formula. Since we want to factor x 3 − 27, we first identify a and b. Since a is the cube root of the first term, we know a = x 3 3 = x . Likewise, since b is the cube root of the second term, we know b = 27 3 = 3 . Step 2. WebThe powers variable in the first term of the binomial descend in an orderly fashion. 2nd degree, 1st degree, 0 degree or 4th degree, 2nd degree, 0 degree. The powers of the variable in the second term ascend in an orderly fashion. 0 degree, 1st degree, 2nd degree. The sign of the 2nd term is negative in the 3rd example, as it should be.
