2x(-2x - y) - ($x^{2}$ - 4xy)
You asked:
Evaluate the expression: \(2 \cdot x \cdot \left(-\left( 2 x \right) - y\right) - \left({x}^{2} - 4 x y\right)\)
MathBot Answer:
Evaluated
\(\displaystyle 2 \cdot x \cdot \left(-\left( 2 x \right) - y\right) - \left({x}^{2} - 4 x y\right) = - x^{2} + 4 x y + 2 x \left(- 2 x - y\right) \)
Expanded
\[2 \cdot x \cdot \left(-\left( 2 x \right) - y\right) - \left({x}^{2} - 4 x y\right) = - 5 x^{2} + 2 x y\]
Factored
\[2 \cdot x \cdot \left(-\left( 2 x \right) - y\right) - \left({x}^{2} - 4 x y\right) = - x \left(5 x - 2 y\right)\]
