If x^2 is in any equation, then it is a parabola
If the abs.val. of x+3 is in an equation, it is not linear, but will look like a straight v since all abs. val. variables are positive.

The first ecuation is a cuadritic ecuation, if you have noticed all the ecuations with a term square X^2 are this type, however the second ecuation is linear because the only x doesn't have any number square. With this easy explanation you will can know the diference between them. Now if you see something like X^3 is a cubic ecuation, x^4 is a fourth ecuation, and so on. I hope you have understood me ; )

equations involving a single power of any number of variable and a constant is linear.
form can be: y=ax+3
y=ax+bz
when powers of the variable increases the equation is no more linear.
equations involving higher powers :
quadratic : y=ax^2+2
y=ax^2+bx+c
ax^2+bxz+cz^2
cubic: y=ax^3+bx^2+cx+d
ur 1st equation is quadratic and second one is linear.
(just look for the power fo variable)

y = ax + b is a linear equation
y = ax^2 + bx + c is a quadratic equation
therefore, your first equation is quadratic and your second is linear.
hope this helps.

yes, it is linear equation
any equ in the form ax^2 + bx +c is a linear equ.
