Name:__________ warm-up 8-6 Use the Distributive Property to factor 20x 2 y + 15xy. Use the Distributive Property to factor 3r 2 t + 6rt – 7r – 14. Solve (4d – 3)(d + 6) = 0Solve 5y 2 = 6y

2
The height h of a ball thrown upward at a speed of 24 feet per second can be modeled by h = 24t – 16t 2, where t is time in seconds. How long will this ball remain in the air before bouncing? Simplify (5y 2 – 3y)(4y 2 + 7y – 8) using the Distributive Property.

3
Details of the Day EQ: When could a non-linear function be used to represent a real world situation? I will be able to… Factor trinomials of the form x 2 + bx + c. Solve equations of the form x 2 + bx + c = 0. Activities: Warm-up Review homework Notes: 8-6 solving quadratic equations Quiz 8-1 & 8-2 Factoring puzzle Class work/ HW Vocabulary: quadratic equation.
