Answer:
His book was opened at Page no.296 and Page no.297
Step-by-step explanation:
Let the page number of one page be x
Page number of page facing page no. x = x+1
We are given that the product of the facing pages was 87,912.
So, x(x+1)=87912




(x+297)(x-296)=0
x=296,-297
Since Page no. cannot be negative
So, x=296
x+1=296+1=297
So, his book was opened at Page no.296 and Page no.297

Answer:
The equation of parabola is standard form is 
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
