What does Quad mean in quadratic equation?
four
The prefix quad means “four” and quadratic expressions are ones that involve powers of x up to the second power, not the fourth power. So why are quadratic equations associated with the number four? As examples: twin, twine (two threads intertwined), twixt, twilight, and the number two itself!
What is the highest power of the variable in quadratic equation?

Because of their wide variety of applications, quadratics have profound historical importance and were foundational to the history of algebra.
Why is quadratic 2 and not 4?
This is the case because quadratum is the Latin word for square, and since the area of a square of side length x is given by x2, a polynomial equation having exponent two is known as a quadratic (“square-like”) equation.

What makes an equation a quadratic equation?
In math, we define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x^2 + 3x + 1.
