You can put this solution on YOUR website!
2 x (3^2x-3) = (5^1-2x)

The rendered equation is 2+x+%283%5E2x-3%29+=+%285%5E1-2x%29.

STEPS

2x%2A3%5E2x-6x=5-2x
18x%5E2-6x=5-2x
18x%5E2-6x%2B2x-5=0
18x%5E2-4x-5=0

Using formula for general solution to a quadratic equation,
discriminant is 16%2B4%2A18%2A5=376=4%2A94=2%2A2%2A2%2A47

x=%284%2B-+sqrt%282%2A2%2A2%2A47%29%29%2F%282%2A18%29
highlight%28x=%282%2B-+sqrt%2894%29%29%2F18%29
