Answer:

2( x +2 )

<em>x+1</em>

Step-by-step explanation:

to add or subtract expressions expand them to make their denominators the same, multiply 1 time \frac{x-2}{x-2}

since \frac{x}{x-2} and \frac{x-2}{x-2} have the same denominators add them by adding their numerators

combine x + x -2

factor x^{2} - 4

to add or subtract expressions expand them and multiply by 1

have same denominator add them by adding their numerators

do the multiplications in 3 + ( x-2 )(x+2)

combine like terms in 3 + x^{2} + 2x - 2x -4

divide \frac{2x-2}{x-2} by \frac{-1 + x^{2} }{(x-2)(x+2) } multiplying \frac{2x-2}{x-2}

cancel out x-2 in both numerator and denominator

factor the expression that are not already factored

cancel out x-1  in both numerator and denominator

expand the expression
