expand (x+2)(x-1-sqrt(7))

expand

(x + 2) (x - 1 - 7)

x^{2} + x (1 - 7) - 27 - 2

Solution steps

(x + 2) (x - 1 - 7)

Distribute parentheses

= xx + x (- 1) + x (- 7) + 2 x + 2 (- 1) + 2 (- 7)

Simplify

xx + x (- 1) + x (- 7) + 2 x + 2 (- 1) + 2 (- 7) : x^{2} + x (1 - 7) - 27 - 2

= x^{2} + x (1 - 7) - 27 - 2

\frac{x}{( x ^{2} + 4 ) ( x + 2 )}

(2 + 32) (3 - 45)

\frac{2 s ^{2} + 10}{( s ^{2} + 4 ) ( s ^{2} - 4 )}

(\frac{1}{5} - x) (\frac{2}{5} - x)

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