How to Find the Vertex of a Quadratic Equation
Yeah, just use x = -b/(2a) and then sub that x into your equation to find y. Super simple once you get the hang of it!

Honestly, use a graphing calculator. It's faster.
To find the vertex, use the formula x = -b/(2a). Once you have the x-value, plug it back into the equation to get the y-value. Voil脿, vertex found!
Use the formula x = -b/(2a). Afterward, substitute x back into the original equation to find y. Done and dusted.
