Question

Write a polynomial function in standard form with the given zeros: -1,2/3

Answer 1

y = (x+1)(3x-2)

Answer 2

x+1=0
-1 -1

x = -1

3x-2=0
+2 +2

3x = 2

divide by 3 on both sides

x = (2/3)

Answer 3

For standard form, expand the equation to the form ax+by=c

Answer 4

Thank you so much!!!

Answer 5

y=(x+1)(3x-2) is not standard, use FOIL:

(x*-2)+(x*3x)+(1*3x)+(1*-2)
