Question

$\frac{ {a}^{ - 1} }{ {a}^{ - 1} + b ^{ - 1} } \frac{ {a}^{ - 1} }{ {a}^{ - 1} - b ^{ - 1} } = \frac{ {2b}^{2} }{ {b}^{2} - a^{2} }$
​

Answer 1

Step-by-step explanation:

When displaying fractions in-line, for example \(\frac{3x}{2}\)

you can set a different display style:

\( \displaystyle \frac{3x}{2} \).

This is also true the other way around

\[ f(x)=\frac{P(x)}{Q(x)} \ \ \textrm{and}

\ \ f(x)=\textstyle\frac{P(x)}{Q(x)} \]
