1–(3x–4x³)²=(1–3x+4x³)(1+3x–4x³)
=[4(x³+1)–3(x+1)][–4(x³–1)+3(x–1)]
=[4(x+1)(x²–x+1)–3(x+1)][–4(x–1)(x²+x+1)+3(x–1)]
=(x+1)(4x²–4x+1)(x–1)(–4x²–4x–1)
=–(x+1)(2x–1)²(x–1)(2x+1)²
=(1–x²)(4x²–1)²
=[4(x³+1)–3(x+1)][–4(x³–1)+3(x–1)]
=[4(x+1)(x²–x+1)–3(x+1)][–4(x–1)(x²+x+1)+3(x–1)]
=(x+1)(4x²–4x+1)(x–1)(–4x²–4x–1)
=–(x+1)(2x–1)²(x–1)(2x+1)²
=(1–x²)(4x²–1)²
