You asked:

Evaluate the expression: \(\left(x + 3\right) \cdot \left(x - 5\right) - \left(2 x + 3\right) \cdot \left(2 x - 5\right)\)

MathBot Answer:

Evaluated



\(\displaystyle \left(x + 3\right) \cdot \left(x - 5\right) - \left(2 x + 3\right) \cdot \left(2 x - 5\right) = - \left(2 x - 5\right) \left(2 x + 3\right) + \left(x - 5\right) \left(x + 3\right) \)

Expanded

\[\left(x + 3\right) \cdot \left(x - 5\right) - \left(2 x + 3\right) \cdot \left(2 x - 5\right) = - 3 x^{2} + 2 x\]

Factored

\[\left(x + 3\right) \cdot \left(x - 5\right) - \left(2 x + 3\right) \cdot \left(2 x - 5\right) = - x \left(3 x - 2\right)\]
