expand x(3^x-3x=69)

Solution

expand

x (3^{x} - 3 x = 69)

Solution

3^{x} x - 3 x^{2} = 69

Solution steps

x (3^{x} - 3 x = 69)

= x (3^{x} - 3 \cdot 69 = x)

Apply the distributive law:

a (b - c) = ab - a c

a = x, b = 3^{x}, c = 3 x = 69

x \cdot 3^{x} - x \cdot 3 x = 69

3^{x} x - 3 xx = 69

Expand

3^{x} x - 3 xx : 3^{x} x - 3 x^{2}

3^{x} x - 3 x^{2} = 69
