"How do you" type questions are answered by explanation.

Explanation:

I use long division:

I am going to use the square root symbol, because I do not find a long division symbol in formatter but please read it as division:

color(white)_color(white)_color(white)_color(white)_x - 2____x−2
2x - 3sqrt(2x^2 - 7x + 19) 2x−3√2x2−7x+19
color(white)_color(white)--2x^2 + 3x_−−2x2+3x
color(white)_color(white)_color(white).color(white)_0 - 4x + 19__._0−4x+19
color(white)_color(white)_color(white)_color(white)_color(white)_4x - 6_____4x−6
color(white)_color(white)_color(white)_color(white)_color(white)_0 + 13_____0+13

The quotient is x - 2x−2 with remainder 13

Written as a mixed number:

x - 2 + 13/(2x - 3)x−2+132x−3
