expand (x-4)(x-2+sqrt(7))

expand

(x - 4) (x - 2 + 7)

x^{2} + x (- 6 + 7) - 47 + 8

Solution steps

(x - 4) (x - 2 + 7)

Distribute parentheses

= xx + x (- 2) + x 7 - 4 x - 4 (- 2) - 47

Simplify

xx + x (- 2) + x 7 - 4 x - 4 (- 2) - 47 : x^{2} + x (- 6 + 7) - 47 + 8

= x^{2} + x (- 6 + 7) - 47 + 8

\frac{e ^{- 0.5 x} ( x + 1 )}{x ( x + 2 ) ( x + 3 )}

\frac{3 ( 3 3 - π )}{27 - π ^{2}}

(x^{5} - 2 x^{2} + 1) l e f t (x^{3} - x^{2} + 1)

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

(x - 4) (x + 1) (x + \frac{1}{2}) (x - \frac{4}{3})
