expand (x^2+7x+9)/((x+1)(x-1))

expand

\frac{x ^{2} + 7 x + 9}{( x + 1 ) ( x - 1 )}

\frac{x ^{2} + 7 x + 9}{x ^{2} - 1}

Solution steps

\frac{x ^{2} + 7 x + 9}{( x + 1 ) ( x - 1 )}

Expand

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

= \frac{x ^{2} + 7 x + 9}{x ^{2} - 1}

(3 i, - i) (i, 8 i)

(x + 5) \circ (x - 3)

(5 x - 2 y) y^{'} (x) + x - y

20 π (x + 4)^{2}

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