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

Solution

simplify

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

Solution

\frac{4}{a}

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{4}{a}

= \frac{4}{a}
