Alright, lets get started.

For making complete square, we will add and subtract 49 in this




Comparing the standard equation of parabola
where (h,k) are vertex
So, comparing the equation with standard one, h, k would be = (-7 , -89)
So, the vertex are (-7 , -89) : Answer
Hope it will help :)
It's easier to add these first and then change to SN.
41,300,000 + 50,500,000 = 91,800,000
SN needs to change to this format:
9.18 x 10^7
Answer:
