Question

Can someone please help me? I'm confused ​

Answer 1

±1, ±2, ±2/3, ±1/3

or

1,2,2/3,1/3,-1,-2,-2/3,-1/3

Explanation:

Start by listing all the factors of the y intercept (in this case 2)

1,2

Then list out all the factors of the coefficent with the highest degree (3 in this case)

1,3

You're then supposed to divide all possible pairs

so all the possible zeroes are

±1, ±2, ±2/3, ±1/3
