You asked:
Evaluate the expression: \({\left( 4 + -2 \right)}^{2} + 4 \cdot -1\)
MathBot Answer:
\[{\left( 4 + -2 \right)}^{2} + 4 \cdot -1 = 0\]
\[\begin{aligned}{\left( 4 + -2 \right)}^{2} + 4 \cdot -1& = \left(4 - 2\right)^{2} + 4 \cdot -1\\& = 2^{2} + 4 \cdot -1\\& = 4 + 4 \cdot -1\\& = 4 - 4\\& = 0\end{aligned}\]
