2. Learning Objectives:
In this Lesson, learners will learn to:

7. a Rational expression is said to be in
simplest form, if the
numerator and the denominator have no
factor in common.

9. a. 16x6y5
10x2y7
= 2• 8• x²•
x4• y5
2• 5• x²•
y²• y5
= 8x4
b. x2-x-12
2x2-7x-4
= (x+3) (x-4)
(2x+1) (x-4)
= x + 3
2x + 1

11. Practice and Application:
• Evaluate each rational expression using
the indicated values or the variables.
1. 5x2 a. when x = 4 and y = 10 b. when x = 0 and y = 11
8y
2. A a. when a = 3 and b = 6 b. when a = -5 and y = 10
b2
