expand (3x+1)(x^2+2x-10)

expand

(3 x + 1) (x^{2} + 2 x - 10)

3 x^{3} + 7 x^{2} - 28 x - 10

Solution steps

(3 x + 1) (x^{2} + 2 x - 10)

Distribute parentheses

= 3 x x^{2} + 3 x \cdot 2 x + 3 x (- 10) + 1 \cdot x^{2} + 1 \cdot 2 x + 1 \cdot (- 10)

Simplify

3 x x^{2} + 3 x \cdot 2 x + 3 x (- 10) + 1 \cdot x^{2} + 1 \cdot 2 x + 1 \cdot (- 10) : 3 x^{3} + 7 x^{2} - 28 x - 10

= 3 x^{3} + 7 x^{2} - 28 x - 10

\frac{4 mn - 8 m ^{2} n - 2 mn}{2 mn}
