You asked:
Investigate the equation: \(-2 \cdot \left(-2 + 1\right) = {\left( -2 \right)}^{2} + 2 \cdot \left(-2 + 1\right)\).
MathBot Answer:
This equation has no unknown quantities, so it is either true or false.
This equation is true because the left-hand side is equal to the right-hand side.
The left-hand side of the equation is:
\[-2 \cdot \left(-2 + 1\right) = 2\]The right-hand side of the equation is:
\[{\left( -2 \right)}^{2} + 2 \cdot \left(-2 + 1\right) = 2\]
