expand (4x+3)(-x^2-5x+9)

expand

(4 x + 3) (- x^{2} - 5 x + 9)

- 4 x^{3} - 23 x^{2} + 21 x + 27

Solution steps

(4 x + 3) (- x^{2} - 5 x + 9)

Distribute parentheses

= 4 x (- x^{2}) + 4 x (- 5 x) + 4 x \cdot 9 + 3 (- x^{2}) + 3 (- 5 x) + 3 \cdot 9

Simplify

4 x (- x^{2}) + 4 x (- 5 x) + 4 x \cdot 9 + 3 (- x^{2}) + 3 (- 5 x) + 3 \cdot 9 : - 4 x^{3} - 23 x^{2} + 21 x + 27

= - 4 x^{3} - 23 x^{2} + 21 x + 27

\frac{4}{16}

(2 x + 3) (3 x + 1)

- 9 \times (- 9)

(\frac{x}{3} + 4)^{3}

48 \times 3
