(2x*2+3y*2-4z*2)-(3x*2+4y*1)
You asked:
Evaluate the expression: \(2 x \cdot 2 + 3 y \cdot 2 - 4 z \cdot 2 - \left(3 x \cdot 2 + 4 y \cdot 1\right)\)
MathBot Answer:
Evaluated
\(\displaystyle 2 x \cdot 2 + 3 y \cdot 2 - 4 z \cdot 2 - \left(3 x \cdot 2 + 4 y \cdot 1\right) = - 2 x + 2 y - 8 z \)
Expanded
\[2 x \cdot 2 + 3 y \cdot 2 - 4 z \cdot 2 - \left(3 x \cdot 2 + 4 y \cdot 1\right) = - 2 x + 2 y - 8 z\]
