5.8 Subtraction of Polynomials Objectives: Students will add polynomials by first collecting like terms. Why? So you can apply addition rules for polynomials in real world applications. Mastery is 80% or better on 5-minute checks and indy practice.

Skill Develop Example 1 Subtract. (5x2 + 3x - 2) - (2x2 + 1) - 1 = 3x2 + 3x - 3

Skill Develop Example 2 Subtract. (2x2y2 + 3xy3 – 4y4) - (x2y2 – 5xy3 + 3y – 2y4) = 2x2y2 + 3xy3 – 4y4 - x2y2 + 5xy3 + 2y4 – 3y = x2y2 + 8xy3 – 2y4 – 3y

Guided Practice Subtract. 1) (5x4 + 4) – (2x2 – 1) 2) (-7m3 + 2m + 4) – (-2m3 – 4) 3) (-3a2b4 + 5ab - 4) - (-4a3 + 11a2b4 – 2a - 6)

Guided Example 3 Subtract. (8x3 + 6x2 – 3x + 5) – (5x3 – 3x2 + 2x – 4) + 4 3x3 + 9x2 - 5x + 9

Think…Ink…Share Example 4 Subtract. (2a4b + 5a3b2 – 4a2b3) – (4a4b + 2a3b2 – 4ab) 2a4b + 5a3b2 – 4a2b3 -4a4b - 2a3b2 + 4ab -2a4b + 3a3b2 – 4a2b3 + 4ab

CFU White Boards Practice Subtract. 1) (-2m3 – 5m2 – 2m – 4) - (m4 – 6m2 + 7m – 10) -m4 -2m3 + m2 -9m + 6 2) (-3x4y3 – 5xy + 2) - (x4y3 + x2 + 2xy + 5) -4x4y3 – 7xy - x2 - 3
