Answer:

Quadratic:

a.

c.

e.

i.

j.

Neither:

f.

h.

Linear:

b.

d.

g.

Step-by-step explanation:

Linear equations are generally expressed in the form y = mx + b - the highest exponent of x is one.

Quadratics are expressed as y = ax^2 + bx + c - the highest exponent of x is two.

Any equation with an exponent of x higher than two is neither linear nor quadratic, but instead cubic or higher.  Therefore we can simply sort these equations by the highest exponent of x present after simplifying.
