how to find x intercepts in vertex form equation We know we can find the x intercepts of the parabola by using the quadratic formula 1st x intercept x b sqrt b 2 4ac 2a 2nd x intercept x b sqrt b 2 4ac 2a The x value of the vertex is located midway between these 2 points If you average the two x intercepts you get their midpoint
Method 1 Completing the Square To convert a quadratic from y ax2 bx c form to vertex form y a x h 2 k you use the process of completing the square Let s see an example Convert y 2x2 4x 5 into vertex form and state the vertex Here s a sneaky quick tidbit When working with the vertex form of a quadratic function and From standard form we can find the vertex and either factor or use the Quadratic Formula to find the x intercepts The intercept form of a quadratic equation is y a x p x q where a is the same value as in
