expand ((x+3)(x+1))/(x^2+2x+3)

expand

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

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

Solution steps

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

Expand

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

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

\frac{( 3 x + 1 ) ( x - 3 )}{( x + 4 )}

(1 - cos (x)) d x

Q (- 1, - 3)

(x^{3} + 8 x^{2} y + 12 y^{2}) d x

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