Answer 1

Объяснение:

$\frac{a {}^{2} - 2ab}{a {}^{2} + 3ab} \times \frac{a {}^{2} b + 3ab {}^{2} }{a {}^{2} - 2a {}^{2} b} =\frac{a\left(a-2b\right)}{a\left(a+3b\right)}\times \left(\frac{a^{2}b+3ab^{2}}{a^{2}-2a^{2}b}\right) =\frac{a-2b}{a+3b}\times \left(\frac{a^{2}b+3ab^{2}}{a^{2}-2a^{2}b}\right) =\frac{a-2b}{a+3b}\times \left(\frac{ab\left(a+3b\right)}{\left(-2b+1\right)a^{2}}\right) =\frac{a-2b}{a+3b}\times \left(\frac{b\left(a+3b\right)}{a\left(-2b+1\right)}\right) =\frac{\left(a-2b\right)b\left(a+3b\right)}{\left(a+3b\right)a\left(-2b+1\right)} =\frac{b\left(a-2b\right)}{a\left(-2b+1\right)} =\frac{ba-2b^{2}}{a\left(-2b+1\right)} =\frac{ba-2b^{2}}{-2ab+a}$
