2(-3)²-5(5)+16
You asked:
Evaluate the expression: \(2 {\left( -3 \right)}^{2} - 5 \cdot 5 + 16\)
MathBot Answer:
\[2 {\left( -3 \right)}^{2} - 5 \cdot 5 + 16 = 9\]
\[\begin{aligned}2 {\left( -3 \right)}^{2} - 5 \cdot 5 + 16& = 2 \cdot \left(-3\right)^{2} - 5 \cdot 5 + 16\\& = 2 \cdot 9 - 5 \cdot 5 + 16\\& = 18 - 5 \cdot 5 + 16\\& = 18 - 25 + 16\\& = -7 + 16\\& = 9\end{aligned}\]
