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

simplify

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

x^{2} - 5 x

Solution steps

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

Distribute parentheses

= 2 \cdot 2 + 2 (- x) + 2 (- x + 4) - x \cdot 2 - x (- x) - x (- x + 4) + x + 4 \cdot 2 + x + 4 (- x) + x + 4 (- x + 4)

Simplify

2 \cdot 2 + 2 (- x) + 2 (- x + 4) - x \cdot 2 - x (- x) - x (- x + 4) + x + 4 \cdot 2 + x + 4 (- x) + x + 4 (- x + 4) : x^{2} - 5 x

= x^{2} - 5 x

2 x ln (3 x) + (9 x^{2} + 2)^{3}

\frac{1}{( n - 1 ) n}

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

x^{x - 1} (ln (x) + \frac{x - 1}{x})

\frac{2}{( s ( s + 1 ) ( s + 4 ) )}
