MathBot Answer:

Evaluated



\(\displaystyle \left(5 x - y\right) \cdot \left(2 x + 1\right) - 2 x - 1 = - 2 x + \left(2 x + 1\right) \left(5 x - y\right) - 1 \)

Expanded

\[\left(5 x - y\right) \cdot \left(2 x + 1\right) - 2 x - 1 = 10 x^{2} - 2 x y + 3 x - y - 1\]

Factored

\[\left(5 x - y\right) \cdot \left(2 x + 1\right) - 2 x - 1 = \left(2 x + 1\right) \left(5 x - y - 1\right)\]
