Lesson Review:
Remember that a rational expression is a fraction. The objective in this lesson is to combine t two algebraic fractions and reduce the answer to the most simplifed form.These expressions can be monimials or polynomials in factored or unfactored form.
THE 4 STEP PROCEDURE IS AS FOLLOWS:
1. Check for common denominator
2. Combine the numerators over the common denominator of only one fraction
3. Cancel terms or factor if possible
4. Reduce and cancel like terms.

2d 2d 2d
ANSWER: 4
2d ::4 over 2d
2)4 - 1 = 1
3a2 3a2 a2
ANSWER: 1
a2 :: 1 over a squared
3) 4k _ k = 1
3k2 3k2 k
ANSWER 1
K:: 1 OVER K
4) 5m + 5m = 2
4m2 4m2 M
ANSWER: 2
M :: 2 over M
5) 2x + x = 3x
3x+1 3x+1 3x+1
ANSWER: 3X
3X+1 :: 3x over 3x+1
**HINT** HINT***: You DON'T cancel the 3x, because they are connected by a +(Plus) sign

y-1 y-1
ANSWER:1
11) 3n-2 _ n-6 = 2n+4
n+4 n+4 n+4
ANSWER: 2n+4
n+4 :: 2n + 4 Over n+4
12) 6x-5 _ 5x-6 = 1
