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

expand

(x - 1) (x + 2) (x + 5)

x^{3} + 6 x^{2} + 3 x - 10

Solution steps

(x - 1) (x + 2) (x + 5)

Expand

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

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

Distribute parentheses

= x^{2} x + x^{2} \cdot 5 + xx + x \cdot 5 - 2 x - 2 \cdot 5

Simplify

x^{2} x + x^{2} \cdot 5 + xx + x \cdot 5 - 2 x - 2 \cdot 5 : x^{3} + 6 x^{2} + 3 x - 10

= x^{3} + 6 x^{2} + 3 x - 10

\frac{- 3 a ^{m - 2}}{- 5 a ^{m - 5}}

a^{5} + 243

35 \cdot 7

(a + 1) (a + 1)

\frac{x ^{2} - 5 x + 6}{x ^{2} - 4}
