expand-14(-2e^{-x^2}x^2+e^{-x^2})

expand

- 14 (- 2 e^{- x^{2}} x^{2} + e^{- x^{2}})

28 e^{- x^{2}} x^{2} - 14 e^{- x^{2}}

Solution steps

- 14 (- 2 e^{- x^{2}} x^{2} + e^{- x^{2}})

Apply the distributive law:

a (b + c) = ab + a c

a = - 14, b = - 2 e^{- x^{2}} x^{2}, c = e^{- x^{2}}

= - 14 (- 2 e^{- x^{2}} x^{2}) + (- 14) e^{- x^{2}}

Apply minus-plus rules

- (- a) = a, + (- a) = - a

= 14 \cdot 2 e^{- x^{2}} x^{2} - 14 e^{- x^{2}}

Multiply the numbers:

14 \cdot 2 = 28

= 28 e^{- x^{2}} x^{2} - 14 e^{- x^{2}}

\frac{( x + 1 ) x ( x - 1 )}{6}

B D + B (C + E) + D^{^{'}} (D + F)

(\frac{a + b}{2}) (\frac{a - b}{2})

\frac{x ^{4} - 4 x ^{3} + 6 x ^{2} ( a + 2 ) \cdot ( b + 3 )}{x ^{2} + 2 x + 1}

\frac{0.1028 x + 0.0842}{( x - 0.9048 ) ( x - 0.6065 )}
