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

expand

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

x^{2} + 2 x - x x - 4 x - 8

Solution steps

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

Distribute parentheses

= xx + x \cdot 4 - x x - x \cdot 4 - 2 x - 2 \cdot 4

Simplify

xx + x \cdot 4 - x x - x \cdot 4 - 2 x - 2 \cdot 4 : x^{2} + 2 x - x x - 4 x - 8

= x^{2} + 2 x - x x - 4 x - 8

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

\frac{100 ( 1.1 - j ^{0.1732} )}{0.9 + j ^{0.1732}}

\frac{( k + 1 ) ^{3}}{4}

3 (x + Δ x^{2})

(x - 5) l e f t (x + 5)
