simplify ((a+1)/a)^2+((a-1)/a)^2

simplify

(\frac{a + 1}{a})^{2} + (\frac{a - 1}{a})^{2}

\frac{2 a ^{2} + 2}{a ^{2}}

Solution steps

(\frac{a + 1}{a})^{2} + (\frac{a - 1}{a})^{2}

(\frac{a + 1}{a})^{2} = \frac{( a + 1 ) ^{2}}{a ^{2}}

(\frac{a - 1}{a})^{2} = \frac{( a - 1 ) ^{2}}{a ^{2}}

= \frac{( a + 1 ) ^{2}}{a ^{2}} + \frac{( a - 1 ) ^{2}}{a ^{2}}

Join

\frac{( a + 1 ) ^{2}}{a ^{2}} + \frac{( a - 1 ) ^{2}}{a ^{2}} : \frac{2 a ^{2} + 2}{a ^{2}}

= \frac{2 a ^{2} + 2}{a ^{2}}

(\frac{a}{2} + \frac{b}{3} + \frac{c}{4})^{2}

\frac{e ^{s} in x ln ( x ) cos ( x )}{x ^{2}}

(\frac{1 + a ^{2} + a}{a + 1}) (\frac{1 - a ^{2} - a}{a - 1})

(x^{\frac{- 2}{3}} \cdot y^{\frac{- 1}{2}})^{2}

7 x^{2} + 11 x y - 6 y^{2}
