5x(5x² - 10x) + 4 (4x - 8)
You asked:
Evaluate the expression: \(5 \cdot x \cdot \left(5 \cdot {x}^{2} - 10 x\right) + 4 \cdot \left(4 x - 8\right)\)
MathBot Answer:
Evaluated
\(\displaystyle 5 \cdot x \cdot \left(5 \cdot {x}^{2} - 10 x\right) + 4 \cdot \left(4 x - 8\right) = 5 x \left(5 x^{2} - 10 x\right) + 16 x - 32 \)
Expanded
\[5 \cdot x \cdot \left(5 \cdot {x}^{2} - 10 x\right) + 4 \cdot \left(4 x - 8\right) = 25 x^{3} - 50 x^{2} + 16 x - 32\]
Factored
\[5 \cdot x \cdot \left(5 \cdot {x}^{2} - 10 x\right) + 4 \cdot \left(4 x - 8\right) = \left(25 x^{2} + 16\right) \left(x - 2\right)\]
