expand

(x + 5) (x^{2} + 3 x - 1)

x^{3} + 8 x^{2} + 14 x - 5

Solution steps

(x + 5) (x^{2} + 3 x - 1)

Distribute parentheses

= x x^{2} + x \cdot 3 x + x (- 1) + 5 x^{2} + 5 \cdot 3 x + 5 (- 1)

Simplify

x x^{2} + x \cdot 3 x + x (- 1) + 5 x^{2} + 5 \cdot 3 x + 5 (- 1) : x^{3} + 8 x^{2} + 14 x - 5

= x^{3} + 8 x^{2} + 14 x - 5

f^{- 1} (4)

\frac{x}{2} + 1

- (\frac{1}{3})^{4}
