What I can Do

DESCRIPTION: Elijah was asked to evaluate and simplify the rational
expressions below. Describe and correct the error in simplifying the rational
expression

1.) 2x² - x-3
---------------------
2x²-11x + 12

2.) 2(x-5)
-----------------
(x-5)(x+2)

Solution :

1.) 2x²-x-3 (x+1)(2x-3)
------------------ = -----------------
2x²-11x+12 (2x-3)(x-4)
=(x+1)(2x=3)
------------------
(2x-3)(x-4)

x+1
= ------------
x-4


2.) 2(x-5) 2(x-5)
--------------- = --------------------
(x-5)(x+2) (x-5)(x+2)
2
= -----------
x + 2

1
= ---------------
x + 1


Process Questions:

1. Is there an error committed by Elijah in number 1. If there is, what is
it?

2. Is there an error committed by Elijah in number 2. If there is, what is
it?

3. What can be divided, common factors or common terms?
