Omar Rayhan Khalif

Who am I?

My name is Omar, i was born March 9th, 2000 in Jakarta. Currently i'm a college student in University of Indonesia, majoring in Naval Architect and Marine Engineering, batch 2018. The reason i chose this major is because i want to make Indonesia's maritime sector become the best in Asia, even in the world, because Indonesia has so much potential in that sector that we haven't explored.

Coding Experience

I was enrolled in a coding class during senior highschool, hosted by Zenius. But it was in the 10th grade, so i'm kind of forgot about all the formulas. But i had some experience in coding as well

ANSWER

1. Manual Answer :

Analysis :

First of all you just have to do some equation with the quadratic number, in this case a squared x. By making it (x+1)(x-1) After that you can eliminate the (x-1) with the same number below, so all you have left is the (x+1). So, for example if x is 1, then the answer is 2.

2. Software Answer (Ms. Excel) :

Ms.Excel

Analysis :

Excel couldnt get the numbers right because, its divided is 0/0, which is an error because Excel substitute the amount of x, which is one, at the very beginning. So the top one is (1^2-1) when the bottom one is (1-1). There you get the result which is 0/0
