solve for x: by completing the square:

(3 x^2 - 4 x + 2)/(3 x - 19) = 0

Multiply both sides by 3 x - 19:

3 x^2 - 4 x + 2 = 0

Divide both sides by 3:

x^2 - (4 x)/3 + 2/3 = 0

Subtract 2/3 from both sides:

x^2 - (4 x)/3 = -2/3

Add 4/9 to both sides:

x^2 - (4 x)/3 + 4/9 = -2/9

Write the left hand side as a square:

(x - 2/3)^2 = -2/9

Take the square root of both sides:

x - 2/3 = (i sqrt(2))/3 or x - 2/3 = -(i sqrt(2))/3

Add 2/3 to both sides:

x = 2/3 + (i sqrt(2))/3 or x - 2/3 = -(i sqrt(2))/3

Add 2/3 to both sides:

Answer: x = 2/3 + (i sqrt(2))/3 or x = 2/3 - (i sqrt(2))/3
