simplify ((x^2)/(y^2))^2-1-((y^2)/(x^2))^2

simplify

(\frac{x ^{2}}{y ^{2}})^{2} - 1 - (\frac{y ^{2}}{x ^{2}})^{2}

\frac{x ^{4}}{y ^{4}} - 1 - \frac{y ^{4}}{x ^{4}}

Solution steps

(\frac{x ^{2}}{y ^{2}})^{2} - 1 - (\frac{y ^{2}}{x ^{2}})^{2}

(\frac{x ^{2}}{y ^{2}})^{2} = \frac{x ^{4}}{y ^{4}}

(\frac{y ^{2}}{x ^{2}})^{2} = \frac{y ^{4}}{x ^{4}}

= \frac{x ^{4}}{y ^{4}} - 1 - \frac{y ^{4}}{x ^{4}}

x^{6} + 2 x^{2} + x^{2}

4 (6 f - 5) + 8 f

\frac{( 16 \cdot ( x + 1 ) ^{4} - x - 1 )}{( x + 2 )}

24 a^{3} + 37 a^{2} - 5 a

(2 cos^{2} (x))^{2}
