x^{3} + 8 x^{2} + 19 x + 12

Solution steps

(x + 1) (x + 4) (x + 3)

Expand

(x + 1) (x + 4) (x + 3) : (x^{2} + 5 x + 4) (x + 3)

= (x^{2} + 5 x + 4) (x + 3)

Distribute parentheses

= x^{2} x + x^{2} \cdot 3 + 5 xx + 5 x \cdot 3 + 4 x + 4 \cdot 3

Simplify

x^{2} x + x^{2} \cdot 3 + 5 xx + 5 x \cdot 3 + 4 x + 4 \cdot 3 : x^{3} + 8 x^{2} + 19 x + 12

= x^{3} + 8 x^{2} + 19 x + 12
