In algebra, a quadratic equation is a second-order equation that can be rearranged in standard form as: ax2 + bx + c = 0
In this equation, x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0.
The term "quadratic" comes from the Latin word "quadratus" which means square. This refers to the fact that the variable x is squared in the equation.
Not every quadratic equation is in standard form. Here are some examples of non-standard quadratic equations:
- Missing the linear coefficient
- Missing the constant termRelated Tests:
