Answer 3

To expand the expression (x + 3)(x - 1)(x - 4), we can use the distributive property of multiplication. Let's break it down step by step:

First, we'll multiply the first two factors:

(x + 3)(x - 1) = x(x) + x(-1) + 3(x) + 3(-1) = x^2 - x + 3x - 3 = x^2 + 2x - 3

Now, we'll multiply the result above by the third factor:

(x^2 + 2x - 3)(x - 4) = (x^2)(x) + (x^2)(-4) + (2x)(x) + (2x)(-4) + (-3)(x) + (-3)(-4) = x^3 - 4x^2 + 2x^2 - 8x - 3x + 12 = x^3 - 2x^2 - 11x + 12

Therefore, the expanded form of (x + 3)(x - 1)(x - 4) is x^3 - 2x^2 - 11x + 12.
