How to Find Quadratic Equation from X Intercepts
It's easy! Suppose your x-intercepts are x1 and x2. The quadratic equation can be written as y = a(x - x1)(x - x2). You just need to find the value of 'a' with some extra info, like a point on the graph.

If x1 and x2 are your x-intercepts, the quadratic equation is (x - x1)(x - x2) = 0. Easy peasy!
From personal experience: once you have the x-intercepts, the formula y = a(x - x1)(x - x2) never fails. Just remember to determine 'a' for accuracy!
Just get the intercepts x1 and x2, and use (x - x1)(x - x2) = 0. Simple as that.
