expand (4x+5)(x^2+4x-7)

expand

(4 x + 5) (x^{2} + 4 x - 7)

4 x^{3} + 21 x^{2} - 8 x - 35

Solution steps

(4 x + 5) (x^{2} + 4 x - 7)

Distribute parentheses

= 4 x x^{2} + 4 x \cdot 4 x + 4 x (- 7) + 5 x^{2} + 5 \cdot 4 x + 5 (- 7)

Simplify

4 x x^{2} + 4 x \cdot 4 x + 4 x (- 7) + 5 x^{2} + 5 \cdot 4 x + 5 (- 7) : 4 x^{3} + 21 x^{2} - 8 x - 35

= 4 x^{3} + 21 x^{2} - 8 x - 35

\frac{3 5}{2 - 2}

(r + 4 t)^{3}

(9 + 5 i) + (- 4 + 4 i)

- 18 a^{3} b + 27 a^{2} b

\frac{132}{3}
