(2x^2-5x-3)/(2x-6) = x+1/2

Explanation:

We can split the numerator up into parts which are monomial multiples of (2x-6), then combine them like this:

(2x^2-5x-3)/(2x-6) = (2x^2-6x+x-3)/(2x-6)

color(white)((2x^2-5x-3)/(2x-6)) = (x(2x-6)+1/2(2x-6))/(2x-6)

color(white)((2x^2-5x-3)/(2x-6)) = ((x+1/2)color(red)(cancel(color(black)((2x-6)))))/color(red)(cancel(color(black)((2x-6))))

color(white)((2x^2-5x-3)/(2x-6)) = x+1/2
