You asked:

Evaluate the expression: \(\left(9 x - 9\right) \cdot \left(7 x - 9\right) + \left(9 x - 9\right) \cdot \left(-\left( 4 x \right) - 6\right)\)

MathBot Answer:

Evaluated



\(\displaystyle \left(9 x - 9\right) \cdot \left(7 x - 9\right) + \left(9 x - 9\right) \cdot \left(-\left( 4 x \right) - 6\right) = \left(- 4 x - 6\right) \left(9 x - 9\right) + \left(7 x - 9\right) \left(9 x - 9\right) \)

Expanded

\[\left(9 x - 9\right) \cdot \left(7 x - 9\right) + \left(9 x - 9\right) \cdot \left(-\left( 4 x \right) - 6\right) = 27 x^{2} - 162 x + 135\]

Factored

\[\left(9 x - 9\right) \cdot \left(7 x - 9\right) + \left(9 x - 9\right) \cdot \left(-\left( 4 x \right) - 6\right) = 27 \left(x - 5\right) \left(x - 1\right)\]
