(6a^3+7a^2) -(5a^3+9a^2+a)=
You asked:
Evaluate the expression: \(6 \cdot {a}^{3} + 7 \cdot {a}^{2} - \left(5 \cdot {a}^{3} + 9 \cdot {a}^{2} + a\right)\)
MathBot Answer:
Evaluated
\(\displaystyle 6 \cdot {a}^{3} + 7 \cdot {a}^{2} - \left(5 \cdot {a}^{3} + 9 \cdot {a}^{2} + a\right) = a^{3} - 2 a^{2} - a \)
Expanded
\[6 \cdot {a}^{3} + 7 \cdot {a}^{2} - \left(5 \cdot {a}^{3} + 9 \cdot {a}^{2} + a\right) = a^{3} - 2 a^{2} - a\]
Factored
\[6 \cdot {a}^{3} + 7 \cdot {a}^{2} - \left(5 \cdot {a}^{3} + 9 \cdot {a}^{2} + a\right) = a \left(a^{2} - 2 a - 1\right)\]
