### Day 23 - Quadratic Factoring - 09.18.14

 Bell RingerBe sure to hand in your Checkpoint sheet each day!Polynomials and Factoring Test on next Friday!Solve the following equation: (x + 3) (2x - 5) = 0x = -3, 5/2x = 3, -5/2x = -3, -5/2x = 3, 5/2none of the aboveSolve the following equation: b(7b - 4) = 0b = 0, 4/7b = 0, -4/7b = 0, 7/4b = 0, -7/4none of the aboveSolve the following equation: 5y2 = -9yy = 0, -9/5y = 0, 9/5y = 0, -5/9y = 0, 5/9none of the aboveFactor the following: z2 - 18z - 40z = -20, 2z = 20, -2z = -20, -2z = 20, 2none of the aboveFactor the following: y2 - y - 42y = -7, 6y = -7, -6y = 7, -6y = 7, 6none of the above ReviewMonomialsPolynomialsAdding/Subtracting PolynomialsMultiplying Polynomials by MonomialsMultiplying Polynomials by PolynomialsSpecial ProductsIntro to FactoringFactoring x2 + bx + cLessonFactoring x2 + bx + cSection 9-3Practice #5-9 (odds)Checkpoint 1 - #4, 6, 8Practice #11-15 (odds)Checkpoint 2 - #10, 12, 14, 16Practice #17-33 (odds)Checkpoint 3 - #30, 32, 34Practice #37-53 (odds)Checkpoint 4 - #48, 50, 52Factoring ax2 + bx + cSection 9-4Practice #5-9 (odds)Checkpoint 1 - #4, 6, 8Practice #15-31 (odds)Checkpoint 2 - #26, 28, 30Practice #35-47Checkpoint 3 - #36, 42, 44, 46, 48Exit TicketPosted on the board at the end of the block Lesson Objective(s)How can expressions of the form ax^2 + bx + c be factored?Standard(s)Mathematical Practice(s)#1 - Make sense of problems and persevere in solving them#2 - Reason abstractly and quantitatively#3 - Construct viable arguments and critique the reasoning of others#6 - Attend to precision#7 - Look for and make use of structure
