GIVEN: $$\frac{-2}{x-2} + \frac{x}{x-3}=$$

Rewrite with common denominators: $$\frac{(-2)(x-3)}{(x-2)(x-3)} + \frac{(x)(x-2)}{(x-3)(x-2)}$$

Simplify numerators: $$\frac{-2x+6}{(x-2)(x-3)} + \frac{x^2-2x}{(x-3)(x-2)}$$

Combine fractions: $$\frac{(-2x+6)+(x^2-2x)}{(x-2)(x-3)}$$

Simplify numerator: $$\frac{x^2-4x+6}{(x-2)(x-3)}$$

Cheers,
Brent
