expand-((2-10y)(2+10y))/((1-2y)(1+2y))

expand

- \frac{( 2 - 10 y ) ( 2 + 10 y )}{( 1 - 2 y ) ( 1 + 2 y )}

- \frac{4 - 100 y ^{2}}{1 - 4 y ^{2}}

Solution steps

- \frac{( 2 - 10 y ) ( 2 + 10 y )}{( 1 - 2 y ) ( 1 + 2 y )}

Expand

(1 - 2 y) (1 + 2 y) : 1 - 4 y^{2}

= - \frac{( - 10 y + 2 ) ( 10 y + 2 )}{- 4 y ^{2} + 1}

Expand

(2 - 10 y) (2 + 10 y) : 4 - 100 y^{2}

= - \frac{- 100 y ^{2} + 4}{- 4 y ^{2} + 1}

(1 - cos (x))^{2} csc^{2} (x)

(4, - 6 i) (4 + 6 i)

y^{\frac{1}{4}} (y^{\frac{3}{4}} + y^{\frac{7}{4}})

\frac{2 \cdot ( x + y ) ^{2}}{3}

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