f(x)= x^-5
(x^2+ 2x)(4 − 3x)(2x^9 + 1)
You asked:
Evaluate the function \(f\left( x \right) = {x}^{-5}\), \(\left({x}^{2} + 2 x\right) \cdot \left(4 - 3 x\right) \cdot \left(2 \cdot {x}^{9} + 1\right)\).
MathBot Answer:
$$\begin{aligned}\left({x}^{2} + 2 x\right) \cdot \left(4 - 3 x\right) \cdot \left(2 \cdot {x}^{9} + 1\right)&=- 6 x^{12} - 4 x^{11} + 16 x^{10} - 3 x^{3} - 2 x^{2} + 8 x\end{aligned}$$
$$\begin{aligned}\left({x}^{2} + 2 x\right) \cdot \left(4 - 3 x\right) \cdot \left(2 \cdot {x}^{9} + 1\right)&=\left(4 - 3 x\right) \left(x^{2} + 2 x\right) \left(2 x^{9} + 1\right)\\\left({x}^{2} + 2 x\right) \cdot \left(4 - 3 x\right) \cdot \left(2 \cdot {x}^{9} + 1\right)&=- 6 x^{12} - 4 x^{11} + 16 x^{10} - 3 x^{3} - 2 x^{2} + 8 x\\\end{aligned}$$
