5a(a+4)-a(2a-3)
You asked:
Evaluate the expression: \(5 \cdot a \cdot \left(a + 4\right) - a \cdot \left(2 a - 3\right)\)
MathBot Answer:
Evaluated
\(\displaystyle 5 \cdot a \cdot \left(a + 4\right) - a \cdot \left(2 a - 3\right) = - a \left(2 a - 3\right) + 5 a \left(a + 4\right) \)
Expanded
\[5 \cdot a \cdot \left(a + 4\right) - a \cdot \left(2 a - 3\right) = 3 a^{2} + 23 a\]
Factored
\[5 \cdot a \cdot \left(a + 4\right) - a \cdot \left(2 a - 3\right) = a \left(3 a + 23\right)\]
