You asked:

Evaluate the expression: \(\left(2 x - 5\right) \cdot \left(5 \cdot \left(x + 1\right) + 2 \cdot \left(x + 2\right)\right) - 4 \cdot x \cdot \left(5 x - 4\right)\)

MathBot Answer:

Evaluated



\(\displaystyle \left(2 x - 5\right) \cdot \left(5 \cdot \left(x + 1\right) + 2 \cdot \left(x + 2\right)\right) - 4 \cdot x \cdot \left(5 x - 4\right) = - 4 x \left(5 x - 4\right) + \left(2 x - 5\right) \left(7 x + 9\right) \)

Expanded

\[\left(2 x - 5\right) \cdot \left(5 \cdot \left(x + 1\right) + 2 \cdot \left(x + 2\right)\right) - 4 \cdot x \cdot \left(5 x - 4\right) = - 6 x^{2} - x - 45\]

Factored

\[\left(2 x - 5\right) \cdot \left(5 \cdot \left(x + 1\right) + 2 \cdot \left(x + 2\right)\right) - 4 \cdot x \cdot \left(5 x - 4\right) = - 6 x^{2} - x - 45\]
