expand 2(9e^x+e^xx)

expand

2 (9 e^{x} + e^{x} x)

18 e^{x} + 2 e^{x} x

Solution steps

2 (9 e^{x} + e^{x} x)

Apply the distributive law:

a (b + c) = ab + a c

a = 2, b = 9 e^{x}, c = e^{x} x

= 2 \cdot 9 e^{x} + 2 e^{x} x

Multiply the numbers:

2 \cdot 9 = 18

= 18 e^{x} + 2 e^{x} x

\frac{x ^{2} ( x + 1 )}{x - 2}

\frac{1}{( m - x ) ( n - x )}

(- 2, 3) y (3, - 1)

\frac{6 x - 11}{( x - 1 ) ^{2}}

\frac{( 3 x - 7 ) ( x - 4 )}{4 x - 6}
