expand (x-2)(x^2+8x-1)

expand

(x - 2) (x^{2} + 8 x - 1)

x^{3} + 6 x^{2} - 17 x + 2

Solution steps

(x - 2) (x^{2} + 8 x - 1)

Distribute parentheses

= x x^{2} + x \cdot 8 x + x (- 1) - 2 x^{2} - 2 \cdot 8 x - 2 (- 1)

Simplify

x x^{2} + x \cdot 8 x + x (- 1) - 2 x^{2} - 2 \cdot 8 x - 2 (- 1) : x^{3} + 6 x^{2} - 17 x + 2

= x^{3} + 6 x^{2} - 17 x + 2

\frac{5 ^{- 1}}{5 ^{2}}

(- 2 + 4 i) + (3 - 9 i)

p - (9.4 q + 3)

- (a + b)

(7 x + 2) (7 x - 2)
