Can someone please help me? I'm confused

±1, ±2, ±2/3, ±1/3

or

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

Step-by-step 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

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
