simplify (x^2-10)e^{-x}

Solution

simplify

(x^{2} - 10) e^{- x}

Solution

\frac{x ^{2} - 10}{e ^{x}}

Solution steps

(x^{2} - 10) e^{- x}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= \frac{1}{e ^{x}} (x^{2} - 10)

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot ( x ^{2} - 10 )}{e ^{x}}

1 \cdot (x^{2} - 10) = x^{2} - 10

= \frac{x ^{2} - 10}{e ^{x}}
