x^2 + 6 = -8x
Is this linear, quadratic or exponential??

  • ALGEBRA -

    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: 4x+4 - 65536 =0

  • ALGEBRA -

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

  • ALGEBRA -

    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 3x+4x = 5x.
    So x² is NOT exponential.

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