Can someone explain a quadratic equation in a way that makes it more intuitively understandable? My algebra teacher just rambles endlessly about unrelated shit.

shit's basic math bruh but your time would be better spent going to khan academy

A quadratic equation is an equation that can be rewritten into the canonical form

0 = a*x^2 + b*x + c

where a, b, and c are specific constants and x is a free variable. A quadratic equation has at most two solutions (a solution is a value of x that makes the equation true) in the real set, but it may have one or no real solutions.

Any quadratic equation in the canonical form can be solved using the quadratic formula:

-b + (+/-square_root(b^2 - 4*a*c) / (2*a))

Note: if b^2 - 4*a*c < 0, then the equation has no real solutions. If it's zero then it has a single real solution. Otherwise it has two real solutions, given by the positive and negative square root.
