Simplifying Rational Algebraic Expressions (RAE) - Grade 8 Math

Introduction to Rational Algebraic Expressions00:00:02

The video introduces the topic of simplifying rational algebraic expressions, requiring knowledge of fractions, laws of exponents, and factoring.

Simplifying Monomials (Example A)00:00:37

Demonstrates simplifying x^2y / 2xy^2 using two methods: subtracting exponents according to the laws of exponents or expanding variables and canceling common terms.

Advanced Factoring (Example B)00:03:09

Explains simplifying (x^2 - 9y^2) / (3xy - 9y^2) using difference of two squares in the numerator and common monomial factoring in the denominator.

Trinomial Factoring (Examples C and D)00:04:48

Covers simplifying more complex expressions like (x^2 - 4) / (x^2 - 2x - 8) and (x^2 - 2x - 3) / (x^2 + 6x + 5) by factoring trinomials and eliminating common binomial factors.
