expand (x+4)(x^2+3x-6)

expand

(x + 4) (x^{2} + 3 x - 6)

x^{3} + 7 x^{2} + 6 x - 24

Solution steps

(x + 4) (x^{2} + 3 x - 6)

Distribute parentheses

= x x^{2} + x \cdot 3 x + x (- 6) + 4 x^{2} + 4 \cdot 3 x + 4 (- 6)

Simplify

x x^{2} + x \cdot 3 x + x (- 6) + 4 x^{2} + 4 \cdot 3 x + 4 (- 6) : x^{3} + 7 x^{2} + 6 x - 24

= x^{3} + 7 x^{2} + 6 x - 24

3 (3 x + 2) + 2

- 12 + (- 3)

3^{4} \cdot 3^{6}

(θ + w i)^{2}

(4 x)^{- \frac{1}{2}}
