Question

Need help solving this derivative:
y=(x^(2)-2)e^(-x)

Answer 1

\[y=(x^2-2)e^(-x)\]

Answer 2

try product rule

Answer 3

ya try the product rule

Answer 4

\[(f*g)' = f'*g + f*g'\]

Answer 5

\[f(x) = x^{2}-2\]
\[f'(x) = 2x\]
\[g(x) = e^{-x}\]
\[g'(x) = -e^{-x}\]

Answer 6

y=\[(x ^{2}-2)e ^{-x}\] then y' will be\[2xe ^{-x}+(x ^{2}-2)e ^{-x}\]

Answer 7

You can use the software Maple to check your answer, and there is a student package that show you the integration step by step.
