Answer:

If I did my math correctly, I believe the answer would be x^3+8x^2+19x+12 (if we were only simplifying, which I think that's what we're doing lol)

Step-by-step explanation:

It's basically just a whole lot of distributing and combining their like terms...

Answer:

x³ + 8x² + 19x + 12

Step-by-step explanation:

(x + 4)(x + 1)(x + 3) ← expand 2nd/ 3rd factors using FOIL

= (x + 4)(x² + 4x + 3)

Each term in the second factor is multiplied by each term in the first factor.

= x(x² + 4x + 3) + 4(x² + 4x + 3) ← distribute parenthesis

= x³ + 4x² + 3x + 4x² + 16x + 12 ← collect like terms

= x³ + 8x² + 19x + 12
