1. 3 + 4x - 4x^2 can be factorized as -4x^2 + 4x + 3 = -(2x - 1)(2x + 3)
2. x^2 - 11x - 12 can be factorized as x^2 - 12x + x - 12 = x(x - 12) + 1(x - 12) = (x + 1)(x - 12)
2. x^2 - 11x - 12 can be factorized as x^2 - 12x + x - 12 = x(x - 12) + 1(x - 12) = (x + 1)(x - 12)

3 × (4x - 4x^2)
= 3 × 4x(1 - x)
= 12x(1 - x)
x^2 - 11x - 12
= x^2 - 12x + x - 12
= x(x - 12) + 1(x - 12)
= (x + 1)(x - 12)
= 3 × 4x(1 - x)
= 12x(1 - x)
x^2 - 11x - 12
= x^2 - 12x + x - 12
= x(x - 12) + 1(x - 12)
= (x + 1)(x - 12)
