How do you find a vertex of a quadratic equation?
Finding the vertex is a breeze! Use x = -b/2a to get the x-value, and then substitute it into the equation to find the y-value. Easy peasy lemon squeezy!

Been there, done that鈥攃alculate x with -b/(2a), and sub it in the equation to get y. Boom, vertex!
To find the vertex of a quadratic equation in the form ax^2 + bx + c, use the formula x = -b/(2a) to find the x-coordinate of the vertex. Plug that x value back into the equation to find the y-coordinate. Voil脿, you have your vertex!
Just use the formula x = -b/(2a) to get the x value, then plug it in for y. It's the quadratic magic!
Honestly, you just need the formula x = -b/2a for the x-coordinate. Everything else falls into place!
