Practice problem
Factor by grouping: 16x3+4x2−4x−116x^3 + 4x^2 - 4x - 116x3+4x2−4x−1
(4x−1)(2x−1)(2x+1)(4x-1)(2x-1)(2x+1)(4x−1)(2x−1)(2x+1)
(4x+1)(2x−1)(2x+1)(4x+1)(2x-1)(2x+1)(4x+1)(2x−1)(2x+1)
(2x2+1)(2x−1)(2x+1)(2x^2+1)(2x-1)(2x+1)(2x2+1)(2x−1)(2x+1)
(2x2−1)(2x+1)(2x^2 -1)(2x+1)(2x2−1)(2x+1)
Type a concept, like “slope” or “photosynthesis”.
