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}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-2%7D%7Bx-2%7D)
since
and
have the same denominators add them by adding their numerators
combine x + x -2
factor
- 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 +
+ 2x - 2x -4
divide
by
multiplying ![\frac{2x-2}{x-2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x-2%7D%7Bx-2%7D)
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
