expand ((y-1)(27y^2+1))/((3y-1)(9y^2+3y+1))

expand

\frac{( y - 1 ) ( 27 y ^{2} + 1 )}{( 3 y - 1 ) ( 9 y ^{2} + 3 y + 1 )}

\frac{27 y ^{3} + y - 27 y ^{2} - 1}{27 y ^{3} - 1}

Solution steps

\frac{( y - 1 ) ( 27 y ^{2} + 1 )}{( 3 y - 1 ) ( 9 y ^{2} + 3 y + 1 )}

Expand

(3 y - 1) (9 y^{2} + 3 y + 1) : 27 y^{3} - 1

= \frac{( y - 1 ) ( 27 y ^{2} + 1 )}{27 y ^{3} - 1}

Expand

(y - 1) (27 y^{2} + 1) : 27 y^{3} + y - 27 y^{2} - 1

= \frac{27 y ^{3} + y - 27 y ^{2} - 1}{27 y ^{3} - 1}

(sec^{2} (x) + csc^{2} (x)) \cdot cos^{2} (x)

112 (\frac{( x + 2 ) ^{2}}{7} + \frac{( y + 5 ) ^{2}}{16} = 1)

\frac{n ^{2} + 2}{( n + 1 ) \cdot 2 ^{n + 1} - n \cdot 2 ^{n}}
