x^2(x+7)+x(x+7)
You asked:
Evaluate the expression: \({x}^{2} \cdot \left(x + 7\right) + x \cdot \left(x + 7\right)\)
MathBot Answer:
Evaluated
\(\displaystyle {x}^{2} \cdot \left(x + 7\right) + x \cdot \left(x + 7\right) = x^{2} \left(x + 7\right) + x \left(x + 7\right) \)
Expanded
\[{x}^{2} \cdot \left(x + 7\right) + x \cdot \left(x + 7\right) = x^{3} + 8 x^{2} + 7 x\]
Factored
\[{x}^{2} \cdot \left(x + 7\right) + x \cdot \left(x + 7\right) = x \left(x + 1\right) \left(x + 7\right)\]
