expand a/((a+b)+b(a+b))

expand

\frac{a}{( a + b ) + b ( a + b )}

\frac{a}{a + b + ab + b ^{2}}

Solution steps

\frac{a}{( a + b ) + b ( a + b )}

Remove parentheses:

(a) = a

= \frac{a}{a + b + b ( a + b )}

Expand

a + b + b (a + b) : a + b + ab + b^{2}

= \frac{a}{a + b + ab + b ^{2}}

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

(e u + u)^{2}

\frac{( k + 1 ) ( 2 k ^{2} + k + 6 )}{6}
