# Lesson 66: Simplifying and Operations on Rational Expressions

Lesson on simplifying rational expressions by factoring. Just like in any expression, it is important for the expression to be in its simplest form. Hence, rational express ions have to be in its simplest form. Factoring the expressions can help simplify the rational expressions.

1:07 (25x+10) /( 5x+2)

2:01 (3x+9) / (2x+6)

3:05 (x^2 +6x +5)/ (x+1)

3:35 (2x^2 +7x+3) / (x+3)

4:38 (m^2 - 9) / (m+3)

5:06 (x^2 -- 25) / (x^2 + 8x +15)
