This means, some quadratic equations might be missing the linear coefficient or the constant term, but they are perfectly valid. For example, \(2{x}^{2}-64=0\) lacks the linear coefficient (b=0), while ... Start with our practice problems at the top of this page and see if you can solve them.
What Is a Quadratic Equation? A quadratic equation is a second-degree polynomial equation in one variable, typically written in the form: ax2+bx+c=0ax^2 + bx + c = 0 a x 2 + b x + c = 0. Where: aa a, bb b, and cc c are constants with aa a not equal to zero. xx x is the variable, and the highest power of xx x (which is 2) defines it as a ...
