Have you learned crossmultiplication? If so: (x)(4x^2) = (2)(8x^2  8x) expand collect like terms isolate for x Does that help?

(x)(4x^2) = (2)(8x^2  8x) 4x^3 = 16x^2  16x 4x^3  16x^2 + 16x = 0 4x(x^2  4x + 4) = 0 For 4x = 0: x = 0 For x^2  4x + 4 = 0: what multiplies to 4 and adds to 4: 2, 2 x^2  4x + 4 = (x  2)^2 (x  2)^2 = 0 x  2 = 0 x = 2
