2. How do you describe quadratic equations?

Step-by-step explanation:

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants where c is also the y-intercept here. They form the curve known as parabola it can be a curved shaped as n(maximum graph) or it can be curved shaped as u(minimum graph). They are solved using the quadratic formula and the values of x that we get by solving are the roots/zeros which means the curve intersects the x-axis at those specific points.

Famous example of a quadratic equation is

The golden ratio is found as the positive solution of the quadratic above quadratic equation.
