expand ((26x^2-y^2)^2)/4

expand

\frac{( 26 x ^{2} - y ^{2} ) ^{2}}{4}

169 x^{4} - 13 x^{2} y^{2} + \frac{y ^{4}}{4}

Solution steps

\frac{( 26 x ^{2} - y ^{2} ) ^{2}}{4}

(26 x^{2} - y^{2})^{2} = 676 x^{4} - 52 x^{2} y^{2} + y^{4}

= \frac{676 x ^{4} - 52 x ^{2} y ^{2} + y ^{4}}{4}

Apply the fraction rule:

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

\frac{676 x ^{4} - 52 x ^{2} y ^{2} + y ^{4}}{4} = \frac{676 x ^{4}}{4} - \frac{52 x ^{2} y ^{2}}{4} + \frac{y ^{4}}{4}

= \frac{676 x ^{4}}{4} - \frac{52 x ^{2} y ^{2}}{4} + \frac{y ^{4}}{4}

Divide the numbers:

\frac{676}{4} = 169

= 169 x^{4} - \frac{52 x ^{2} y ^{2}}{4} + \frac{y ^{4}}{4}

Divide the numbers:

\frac{52}{4} = 13

= 169 x^{4} - 13 x^{2} y^{2} + \frac{y ^{4}}{4}

(1 - \frac{1 - 240 x}{T x + 1}) (T x + 1)

(a - 5) (a + 1) (1 + \frac{3 a - 37}{a ^{2} - 4 a - 5})

(z + 1 + 4 i)^{2}

x^{2} d x (x - 4)

(1 - \frac{207}{n}) (1 - \frac{207}{n - 414})
