You asked:

Evaluate the expression: \(5 a + \left(2 a - 3 b\right) \cdot \left(3 a - b\right) - \left(a + 2 b\right) + a b - 3 b\)

MathBot Answer:

Evaluated



\(\displaystyle 5 a + \left(2 a - 3 b\right) \cdot \left(3 a - b\right) - \left(a + 2 b\right) + a b - 3 b = a b + 4 a - 5 b + \left(2 a - 3 b\right) \left(3 a - b\right) \)

Expanded

\[5 a + \left(2 a - 3 b\right) \cdot \left(3 a - b\right) - \left(a + 2 b\right) + a b - 3 b = 6 a^{2} - 10 a b + 4 a + 3 b^{2} - 5 b\]

Factored

\[5 a + \left(2 a - 3 b\right) \cdot \left(3 a - b\right) - \left(a + 2 b\right) + a b - 3 b = 6 a^{2} - 10 a b + 4 a + 3 b^{2} - 5 b\]
