MathBot Answer:
Evaluated
\(\displaystyle \left(2 a - 3 b\right) \cdot \left(5 - a + 2 b\right) = \left(2 a - 3 b\right) \left(- a + 2 b + 5\right) \)
Expanded
\[\left(2 a - 3 b\right) \cdot \left(5 - a + 2 b\right) = - 2 a^{2} + 7 a b + 10 a - 6 b^{2} - 15 b\]
Factored
\[\left(2 a - 3 b\right) \cdot \left(5 - a + 2 b\right) = - \left(2 a - 3 b\right) \left(a - 2 b - 5\right)\]
