expand ((x+2)(x-2))/((x-4)(x+1))

expand

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

\frac{x ^{2} - 4}{x ^{2} - 3 x - 4}

Solution steps

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

Expand

(x - 4) (x + 1) : x^{2} - 3 x - 4

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

Expand

(x + 2) (x - 2) : x^{2} - 4

= \frac{x ^{2} - 4}{x ^{2} - 3 x - 4}

\frac{4 ( 3 ^{n} + 2 ^{n} )}{( 3. 3 ^{n} + 2. 2 ^{n} )}

\frac{y ^{''} ( x ) ( x ^{4} - x ) ^{5}}{6}

\frac{( 1 - x ) y}{x}

\frac{5 ( 9 + 21 )}{3}

(0.3 e^{- x} + 0.4 + 0.3 e^{x})^{2}
