How do you factor #x^15 - 1/64#? Algebra Polynomials and Factoring Factor Polynomials Using Special Products 1 Answer Shwetank Mauria Apr 28, 2016 #x^15-1/64=(x^5-1/4)(x^(10)+1/4x^5+1/16)# Explanation: #x^15-1/64=(x^5)^3-(1/4)^3# and hence using identity #a^3-b^3=(a-b)(a^2+ab+b^2)#, we get #(x^5)^3-(1/4)^3=(x^5-1/4)((x^5)^2+1/4x^5+(1/4)^2)# = #(x^5-1/4)(x^(10)+1/4x^5+1/16)# Answer link Related questions How do you factor special products of polynomials?
