This post about forms of quadratic equations. In this post general quadratic equations with graph.This post is also include important facts quadratics like vertex , x-intercept and y-intercepts. The quadratic equation is an important topic in all syllabus like IB and cambridge etc
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, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant “a” cannot be a zero.
