YoungMath & Expert Subjects presents Texas Algebra I, Lesson 7:Simplifying Algebraic Expressions Mrs. Young
Define “like terms” • Identify like terms in a given algebraic expression or equation • Simplify expressions/equations by combining like terms Lesson Objectives:
examples Counterexamples (non-examples) • 4x, 3x • 9, 13 • 14xyz, xyz • 4, 3x • 5g, 2g2 • 23xyz, 2xy Like terms- Like terms are terms that contain the same variables raised to the same power.
3x + 4b –x 3y -5xy +17 –y + (-4xyz) 2x2 +3x -5 +7 + 9x + 5x2 Guided Practice:expressions
Directions: Simplify. 2x – 3y = 7x + y – 5 6jkl + 4j – 8klj = 21j – 102 21θ – 32 = 45 – θ + 3θ2 Guided Practice:equations
