expand (2-sqrt(x-3))/((x+7)(x-7))

expand

\frac{2 - x - 3}{( x + 7 ) ( x - 7 )}

\frac{2 - x - 3}{x ^{2} - 49}

Solution steps

\frac{2 - x - 3}{( x + 7 ) ( x - 7 )}

Expand

(x + 7) (x - 7) : x^{2} - 49

= \frac{2 - x - 3}{x ^{2} - 49}

\frac{lo g _{10} ( x )}{( lo g _{10} ( x ) + 1 ) ^{2}}

\frac{x ^{3} - 8 x ^{2} - 1}{( x + 3 ) ( x - 2 ) ( x ^{2} + 1 )}

(e^{- x} - x)^{2}

(1 + y^{2}) d x + (x^{2} y + y) d y

\frac{20}{( S + 1 ) ( S ^{2} + 4 S + 13 )}
