True or False. The equation 4x2 + 16 = 0 is an example of a quadratic equation. Explain. I think it's false because a quadratic equation needs to be in the form of ax^2 + bx +c = 0... I have a feeling I'm wrong though..

    it is of that form...a=4,b=0,c=16

    yeah b is just zero, and that is fine

    It contains a second power of x as its highest power so it is quadratic.

    In other words, it is a second degree equation so it is quadratic.

    but could C be zero too? ax^2 + 16 + 0 =0 ?

    ooooh ok, the second degree equation rings a bell

    Yes a quadratic equation is of the form ax^2 +bx+c where a is not 0. b and c can be 0 but not a

    x^2=0 x^+3x=0 x^2-5x+7=0 All are quadratic equations.
