expand (x(x-1))/((4+x)(4-x))

expand

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

\frac{x ^{2} - x}{16 - x ^{2}}

Solution steps

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

Expand

(4 + x) (4 - x) : 16 - x^{2}

= \frac{x ( x - 1 )}{16 - x ^{2}}

Expand

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

= \frac{x ^{2} - x}{16 - x ^{2}}

5 (6 - 8)

e^{j (z_{1} + z_{2})}

(5 + x) x^{4} e^{7 x}

x (3 - x)

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