3(a+1)^2 - (a+1) + 2
You asked:
Evaluate the expression: \(3 \cdot {\left( a + 1 \right)}^{2} - \left(a + 1\right) + 2\)
MathBot Answer:
Evaluated
\(\displaystyle 3 \cdot {\left( a + 1 \right)}^{2} - \left(a + 1\right) + 2 = - a + 3 \left(a + 1\right)^{2} + 1 \)
Expanded
\[3 \cdot {\left( a + 1 \right)}^{2} - \left(a + 1\right) + 2 = 3 a^{2} + 5 a + 4\]
Factored
\[3 \cdot {\left( a + 1 \right)}^{2} - \left(a + 1\right) + 2 = 3 a^{2} + 5 a + 4\]
