Quizplus · Accepted Answer

A quadratic equation is an equation where the highest power of the variable is 2. In this equation, the highest power of x is 1, therefore it is not a quadratic equation. A quadratic equation is an equation with a degree of two which means it has a variable raised to the second power. The given equation, x + 5 = 0, only has a variable raised to the first power which means it is a linear equation not a quadratic equation.
