expand 4(3e^{-x}x^2-e^{-x}x^3)

expand

4 (3 e^{- x} x^{2} - e^{- x} x^{3})

12 e^{- x} x^{2} - 4 e^{- x} x^{3}

Solution steps

4 (3 e^{- x} x^{2} - e^{- x} x^{3})

Apply the distributive law:

a (b - c) = ab - a c

a = 4, b = 3 e^{- x} x^{2}, c = e^{- x} x^{3}

= 4 \cdot 3 e^{- x} x^{2} - 4 e^{- x} x^{3}

Multiply the numbers:

4 \cdot 3 = 12

= 12 e^{- x} x^{2} - 4 e^{- x} x^{3}

(x + 1) (- csc^{2} (x))

(a 2 + b 3)^{(4)}

(2 x - 1)^{3} cosh (4 x)

\frac{n ( n + 1 ) ( 2 n + 7 )}{6}

(sin^{(4)} (θ) - cos^{(4)} (θ) + 1) csc^{2} (x)
