You asked:

Evaluate the expression: \(2 \cdot x \cdot \left({x}^{2} - 4\right) - {\left( x + 3 \right)}^{2} + 11 x + 9\)

MathBot Answer:

Evaluated



\(\displaystyle 2 \cdot x \cdot \left({x}^{2} - 4\right) - {\left( x + 3 \right)}^{2} + 11 x + 9 = 2 x \left(x^{2} - 4\right) + 11 x - \left(x + 3\right)^{2} + 9 \)

Expanded

\[2 \cdot x \cdot \left({x}^{2} - 4\right) - {\left( x + 3 \right)}^{2} + 11 x + 9 = 2 x^{3} - x^{2} - 3 x\]

Factored

\[2 \cdot x \cdot \left({x}^{2} - 4\right) - {\left( x + 3 \right)}^{2} + 11 x + 9 = x \left(2 x - 3\right) \left(x + 1\right)\]
