n(n-3)+3(n+5)
You asked:
Evaluate the expression: \(n \cdot \left(n - 3\right) + 3 \cdot \left(n + 5\right)\)
MathBot Answer:
Evaluated
\(\displaystyle n \cdot \left(n - 3\right) + 3 \cdot \left(n + 5\right) = n \left(n - 3\right) + 3 n + 15 \)
Expanded
\[n \cdot \left(n - 3\right) + 3 \cdot \left(n + 5\right) = n^{2} + 15\]
Factored
\[n \cdot \left(n - 3\right) + 3 \cdot \left(n + 5\right) = n^{2} + 15\]
