unit 3 polynomial functions
The Binomial Square Theorem Tune – “Yankee Doodle Dandy” by John A Carter - Chicago, IL (x + y) *2 ≠ x^2 + y^2 x + y quan-ti-ty squared Is NOT x squared plus y squared ‘Cause if you try to FOIL it out A middle term has ap-peared. (x + y)*2 = x^2 + 2xy + y^2 You can use this form-u-la. Standard Form"
(Lyrics by Caroline King & Kathy Myron Tune - "Jingle Bells”) Ax^2 + Bx + C = 0 This quadratic’s in standard form. Solve it and be a hero. B.I.N.G.O. Poly
Written by J. Blackwell There is a way to multiply a poly times a poly. Corner the Box Method – Fill the chart with terms – Square or rectangle – It really does not matter. Quadratic Formula
Tune “Are You Sleeping” Negative b – Plus or minus square root – B squared minus 4 a c – All over 2a (repeat each line segment twice.) Factoring (new lyrics by Jill Nielsen Tune - "McDonald’s Jingle – You Deserve a Break Today") Factoring polynomials, It’s so easy to do. When you know the four ways. You can do it all day. GCF, and Perfect Square, Difference of Squares, and I Method In McAlgebra, YOU do it all for you. |
The Poly Dance By John A. Carter – Chicago, IL Melody: "Hokey Pokey" You put your right hand out, You put your left hand out, You can even flip direction Or jump straight up and down. NOW that’s a constant function And it makes you want to shout, “Polynomials can dance about!” You put your right hand up, You put your left hand down, You can alternate direction Or jump straight up and down. NOW that’s a linear function And it makes you want to shout, “Polynomials can dance about!” You put your right hand up, You put your left hand up, You can even flip direction Or jump straight up and down. NOW that’s a quadratic function And it makes you want to shout, “Polynomials can dance about!” You put your right hand up, You put your left hand down, You can alternate direction Or jump straight up and down. NOW that’s a cubic function And it makes you want to shout, “Polynomials can dance about!” Problem Solving Strategies
(Lyrics by Jill Nielsen & Sheila Kotter Tune - "Frere Jacques”) Problem solving Strategies Are here for you Here’s what you do: Draw a little picture; Make a list or graph; put diagrams in you plan. Look for patterns In the problems; What the heck, Guess and check; Solve a simpler problem; Did you try it backwards? Do answers make sense? They must make sense. |
