To convert the vertex to standard form: Expand the square, (x−h)2(x−h)2.Distribute aa.Combine the like terms. We know that the vertex form of parabola is y=a(x−h)2+ky=a(x−h)2+k. How to Convert Vertex Form to Standard Form? This calculator shows you how to convert it into the vertex form with a step-by-step explanation. You can enter the equation of the parabola in the standard form. Here is the “Standard Form to Vertex Form Calculator.” Here, DD is the discriminant where, D=b2−4acD=b2−4ac. Apply the following formulas to find the values the values of hh and kk and substitute it in the vertex form (y=a(x−h)2+ky=a(x−h)2+k):.Compare the given equation with the standard form (y=ax2+bx+cy=ax2+bx+c) and get the values of a,b,a,b, and cc.If the above process seems difficult, then use the following steps: This is of the form a(x−h)2+ka(x−h)2+k, which is in the vertex form. Step 5: Simplify the last two numbers and distribute the outside number. The above expression from Step 3 becomes: Step 4: Factorize the perfect square trinomial formed by the first 3 terms using the suitable identity Step 3: Add and subtract the above number after the xx term in the expression.

Step 2: Make it half and square the resultant number. If the coefficient of x2x2 is NOT 11, we will place the number outside as a common factor. Let us learn how to complete the square using an example.Ĭonvert the parabola from standard to vertex form:įirst, we should make sure that the coefficient of x2x2 is 11 So to convert the standard form to vertex form, we just need to complete the square. In the vertex form, y=a(x−h)2+ky=a(x−h)2+k, there is a “whole square.” If a<0a<0, the parabola has maximum value at (h,k)(h,k). If a>0a>0, the parabola has minimum value at (h,k)(h,k) and.In the vertex form, (h,k)(h,k) represents the vertex of the parabola where the parabola has either maximum/minimum value.The vertex form of a parabola is: y=a(x−h)2+ky=a(x−h)2+k Xx and yy are variables where (x,y)(x,y) represents a point on the parabola. Here, a,b,a,b, and cc are real numbers (constants) where a≠0a≠0.
The standard form of a parabola is: y=ax2+bx+cy=ax2+bx+c How to Convert Standard Form To Vertex Form? Standard Form Tips and Tricks on Standard Form to Vertex Form Important Notes on Standard Form to Vertex Form How to Convert Standard Form To Vertex Form?
