expand (y^8+2y^4+1)/(4y^4)

expand

\frac{y ^{8} + 2 y ^{4} + 1}{4 y ^{4}}

\frac{y ^{4}}{4} + \frac{1}{2} + \frac{1}{4 y ^{4}}

Solution steps

\frac{y ^{8} + 2 y ^{4} + 1}{4 y ^{4}}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{y ^{8} + 2 y ^{4} + 1}{4 y ^{4}} = \frac{y ^{8}}{4 y ^{4}} + \frac{2 y ^{4}}{4 y ^{4}} + \frac{1}{4 y ^{4}}

= \frac{y ^{8}}{4 y ^{4}} + \frac{2 y ^{4}}{4 y ^{4}} + \frac{1}{4 y ^{4}}

Cancel

\frac{y ^{8}}{4 y ^{4}} : \frac{y ^{4}}{4}

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

Cancel

\frac{2 y ^{4}}{4 y ^{4}} : \frac{1}{2}

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

e^{i t} (- i + 1)

\frac{y ^{'} ( t )}{( m ( t ) - y ) ( y - m ( t ) )}

5 (2 x y^{2} + 2 y \frac{d}{d x} ((y) x^{2}))

r (2, 2, - 1) \cdot s (1, - 2, 3)

ln (7 x^{2})
