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

expand

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

4 x^{3} - 7 x^{2} - 23 x - 10

Solution steps

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

Distribute parentheses

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

Simplify

4 x x^{2} + 4 x (- 3 x) + 4 x (- 2) + 5 x^{2} + 5 (- 3 x) + 5 (- 2) : 4 x^{3} - 7 x^{2} - 23 x - 10

= 4 x^{3} - 7 x^{2} - 23 x - 10

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

\frac{16 x ^{6} y ^{5} z - 12 x ^{4} y ^{6} z ^{2} + 6 x ^{3} y ^{9}}{- 4 x ^{2} y}

4 x^{2} + 9 y^{2} - 12 x y

(x - 1) \cdot (x - 2)
