expand (y+2z-x)/((y+2z)^2)

expand

\frac{y + 2 z - x}{( y + 2 z ) ^{2}}

\frac{y + 2 z - x}{y ^{2} + 4 yz + 4 z ^{2}}

Solution steps

\frac{y + 2 z - x}{( y + 2 z ) ^{2}}

(y + 2 z)^{2} = y^{2} + 4 yz + 4 z^{2}

= \frac{y + 2 z - x}{y ^{2} + 4 yz + 4 z ^{2}}

(7 x + 3 y = - 2, 6) (4 x + y = - 4)

\frac{\partial}{\partial u} ((f (u)) (1, - 1))

\frac{( 120 - x ) ^{2}}{4}

(\frac{3 x - y}{3})^{14}

\frac{( 16 + x - 4 ) ( x + 2 ) ( 9 + x + 3 )}{x}
