x^2 + 6 = -8x

Question

Is this linear, quadratic or exponential??

Answer 1

Linear will have terms containing variables not raised to any power, as well as constant terms.
Example: 2y+4x-3=0

A quadratic expression will have terms containing the variable raised to a maximum power of 2.
Example: x²+3x-4=0

An exponential expression will have terms which raise to a power containing the variable.
Example: 4^{x+4 - 65536 =0}

Answer 2

So with the X being squared it would be exponential then?

Answer 3

x² 's exponent does not contain x, so it is not exponential.
It is exponential when the variable (for example, x) is found in the exponent, as in 3^x+4^x = 5^x.
So x² is NOT exponential.

If you reread the examples, it will be much clearer.
