Answer:- 1) there are three terms
2) 3,4,1
Answer:

Step-by-step explanation:
The equation of a parabola: y = ax²
The larger the value of |a|, the narrower the parabola.
We have the following coefficients a:

We arrange the coefficients from the smallest to the largest:

Therefore you have the answer:

You have to divide both by common factor, in this case it's 12
So 72/60 = 6/5
Thus, 6/5 is the simplest form.
