expand (x-1)(x^2+3x-5)

expand

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

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

Solution steps

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

Distribute parentheses

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

Simplify

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

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