Answer:


7x^2 - 40x + 12 = 0

Explanation:

The equation
(5x-2)/(2)-(19x-6)/(2x)=(3x-2)/(4) can be written as a quadratic with the following steps:

  1. Multiply each term by 4x to clear all denominators.
  2. Apply the distributive property.
  3. Combine like terms.
  4. Move all terms to one side.

Step 1 :


(5x-2)/(2)-(19x-6)/(2x)=(3x-2)/(4)\\4x((5x-2)/(2)-(19x-6)/(2x)=(3x-2)/(4))\\2x(5x-2) -2(19x-6) = x(3x-2)

Step 2:


2x(5x-2) -2(19x-6) = x(3x-2)\\10x^2 - 4x - 38x + 12 = 3x^2 - 2x

Step 3:


10x^2 - 4x - 38x + 12 = 3x^2 - 2x\\10x^2 - 42x + 12 = 3x^2 - 2x

Step 4:


10x^2 - 42x + 12 = 3x^2 - 2x\\7x^2 - 40x + 12 = 0
