a(3a+2)-2b(b-4)
You asked:
Evaluate the expression: \(a \left(3 a + 2\right) - 2 b \left(b - 4\right)\)
MathBot Answer:
Evaluated
\(\displaystyle a \left(3 a + 2\right) - 2 b \left(b - 4\right) = a \left(3 a + 2\right) - 2 b \left(b - 4\right) \)
Expanded
\[a \left(3 a + 2\right) - 2 b \left(b - 4\right) = 3 a^{2} + 2 a - 2 b^{2} + 8 b\]
Factored
\[a \left(3 a + 2\right) - 2 b \left(b - 4\right) = 3 a^{2} + 2 a - 2 b^{2} + 8 b\]
