What are the factors of ? Written in simplest factored form, the binomial can be expressed as (1) 2(x 5)(x 5) (3) (x 5)(x + 5) – – – (2) 2(x 5)(x + 5) (4) 2x(x 50) – – Factor completely: If is one factor of , what is the other factor? 15. Use the diagram below to answer the following questions: Find the area of the shaded region, in terms of x. If the area of the shaded region is 40 , what is the value of x? Class work Sketch the graphs of the following functions, clearly marking all intercepts, the axis of symmetry, and the vertex of the curve. 1. y = (x - 2)(x + 4) a. x int ______________________________ – b. y int ______________________________ – c. Axis of Symmetry ____________________
