Insert the vertex coordinates into the equation y= a(x-h)^2 + k, where h is the x-value and k is the y-value. The value of a comes from the original equation. y = 3(x+1)^2+5 This is the vertex form of the parabola's equation. (The h is a +1 in the equation because ...

where "x" and "y" are variables and "a," "b" and "c" are integers. For instance, y = 2x^2 + 8x – 10 is in standard form, whereas y – 8x = 2x^2 – 10 is not. In the latter equation, add 8x to both sides to put it in standard...

Step 1: To convert a general (standard) form of a quadratic equation ax2+bx+c=0 to the vertex form a(x−h)2+k=0, find h, the x-coordinate of the vertex, by computing h=−b2a. Step 2: Find k, the y-coordinate of the vertex, by substituting the x-coordinate of t...
Vertex form of a quadratic equation given two points: vertex (h, k) and other point (x, y). Vertex form formula: y = a(x-h)2 + k Vertex form of a quadratic equation is y = a(x-h)2 + k, where (h, k) is the vertex of the parabola. The vertex of a parabola is the po...
First, we'll take that−314and move it over to the left side of the equation: y+314=7x2+42x The next step is to factor out the 7 (theavalue in the equation) from the right side, like so: y+314=7(x2+6x) Great! This equation is looking much more like vertex form,y=a(x...

No, you don't need to put the equation in vertex form. Just do as jedishrfu suggests, and substitute the four pairs of x- and y-values into the equation y = ax^2 + bx + c. I've checked, and can verify that all four of the given points lie on the same parabola.FAQ: How ...
Putting the equation of a conic in its standard form gives us a series of information such as its center, vertex, and the axis of symmetry, among other data that must be determined when doing a study of conics. To put a conic into its standard form, the square completion method is ...
