Each person was to have 1.5 pounds of turkey, but, with the extra people she would have to buy an additional 4.5 pounds of turkey. If she didn’t buy anymore turkey then everyone would get 1.25 pounds of turkey, which is about 1/6 less of what they would have originally gotten. 1/6 is equal to 16.7% or 0.167.

Answer:
3y^2 - (y + 2) (y - 2) = 0
<=> 3y^2 - (y^2 - 4) = 0
<=> 2y^2 + 4 =0
<=>y^2 + 2 = 0
=> Because y^2 is always equal or larger than 0, there is no real solution.
Hope this helps!
