Q:
# A polynomial function can be written as (x + 2)(x + 3)(x β 5). What are the x-intercepts of the graph of this function?

Accepted Solution

A:

(-2,0) (-3,0) (5,0)

Make each factor or parentheses equal to zero and solve to get the x value of the intercepts.

x+2 = 0

subtract 2 from both sides

x = -2

x+3 = 0

subtract 3 from both sides

x = -3

x-5 = 0

add 5 to both sides

x = 5

Make each factor or parentheses equal to zero and solve to get the x value of the intercepts.

x+2 = 0

subtract 2 from both sides

x = -2

x+3 = 0

subtract 3 from both sides

x = -3

x-5 = 0

add 5 to both sides

x = 5
