Write a polynomial of degree 3 whose only roots are x=2 and x=2/5. is there another polynomial of degree 3 that has the same roots?

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
