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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

31 x - 3 + 4

L (x) (y^{4} - y = sinh (x))

(3 y d x + 6 d x - x d y = 0) \frac{1}{y d y}

\frac{( x + 4 ) ( 6 x - 1 )}{6}

\frac{1}{( x + h + 5 ) ^{2}}
