No. Y=3X2+1 is a Binomial Equation.
A linear equation is defined as an equation that contains only the first power of the unknown quantity. For example, 5x - 3 = 7 where "x" is the unknown quantity is a linear equation. If an equation contains an unknown quantity having a higher power than 1, then the equation ceases to be a linear equation. For example, 3x2 + 5x + 7 = 0 is a non linear equation known as a quadratic equation, because the unknown quantity "x" has a power of 2. Similarly, equations containing unknowns with higher powers such as x3, x7, x12 are all non linear equations.
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
x = +/- sqrt(y/3)

Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
Yes.
y2=x3+3x2
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x

It is non-linear. Try graphing it, and see:Calculate y, when x equals various values, such as -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, and 5.Then, plot the points. Do they lie on a straight line? No, they lie on a bullet-shaped curve, called a parabola, if you have plotted the points correctly.A quadratic function in x is one whose highest term is a multiple of x2, and the graph of any quadratic function has a shape like that described above; not a straight line.
X = 5 or -5 3x2 - 42 = 33 3x2 = 75 x2=25
