Hello! So, there is a rule that says if you are adding or subtracting something with a common denominator, you can put the numerators together and simplify. \(\:\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\) Which applying to your equation gives \(=\frac{x-2+4x-4}{6x^2+6x}\)
which you then simplify to \(=\frac{5x-6}{6x^2+6x}\)
