How to solve such questions?
Such Questions can be easily solved just by some Algebraic manipulations and simplifications. We just try to make our expression in the form which question asks us. This is the best method to solve such questions as it will definitely lead us to correct answers. One such method is completing the square method.
Completing the square is a method that is used for converting a quadratic expression of the form
to the vertex form
. The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square:
, such that the left side is a perfect square trinomial
= 
=

=
On comparing with the given equation we get
p = -
and q = 
∴
= 
= - 34

Answer:
3/25
Step-by-step explanation:
This is because when you divide 12/100 and simplify. All you need to focus on is that there are 100 tiles and twelve of them are with the letter E the simplify from there. all the other information is just there to distract you.
So the answer is D hope this would help you
