Answer:
2( x +2 )
x+1
Explanation:
to add or subtract expressions expand them to make their denominators the same, multiply 1 time
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
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
