Step-by-step explanation:
Given equation of parabola is,
In order to find the equation of parabola in standard form, eliminate x from left side of equation and use completing square method to find the equation.
First step is to add x on both side of equation.
Rewriting,
Now applying completing square method as follows.
Following are the steps for calculation of this method.
Find the last term of above equation by using below formula,
Now coefficient of y is 8.
Simplifying,
Second step is to add and subtract the last term.
Rewriting,
Since
Using above formula,
Therefore, the equation of parabola in standard form is
