# Reducing the expression (a2 - b2 / ab) - (ab - b2 / ab - a2) to the lowest terms, we get _____.

Dear student
$\left(\frac{{\mathrm{a}}^{2}-{\mathrm{b}}^{2}}{\mathrm{ab}}\right)-\left(\frac{\mathrm{ab}-{\mathrm{b}}^{2}}{\mathrm{ab}-{\mathrm{a}}^{2}}\right)\phantom{\rule{0ex}{0ex}}⇒\left(\frac{{\mathrm{a}}^{2}-{\mathrm{b}}^{2}}{\mathrm{ab}}\right)-\frac{\mathrm{b}\left(\mathrm{a}-\mathrm{b}\right)}{\mathrm{a}\left(\mathrm{b}-\mathrm{a}\right)}\phantom{\rule{0ex}{0ex}}⇒\left(\frac{{\mathrm{a}}^{2}-{\mathrm{b}}^{2}}{\mathrm{ab}}\right)+\frac{\mathrm{b}}{\mathrm{a}}\phantom{\rule{0ex}{0ex}}⇒\frac{{\mathrm{a}}^{2}-{\mathrm{b}}^{2}+{\mathrm{b}}^{2}}{\mathrm{ab}}\phantom{\rule{0ex}{0ex}}⇒\frac{{\mathrm{a}}^{2}}{\mathrm{ab}}\phantom{\rule{0ex}{0ex}}⇒\frac{\mathrm{a}}{\mathrm{b}}\phantom{\rule{0ex}{0ex}}$
