A variable is a letter in the equation.
A, B, and C dont have variables... unless a question mark is considered a variable at your school (I dont consider it a variable).
D has an x in the equation, so D has a variable.
<h3><u>Given :- </u></h3>
![A=\left[\begin{array}{ccc}1&4\\5&6\\\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%264%5C%5C5%266%5C%5C%5Cend%7Barray%7D%5Cright%5D)
- a
= 6
<h3><u>To Find :- </u></h3>
<h3><u>Solution:- </u></h3>
In a matrix the the the position of an element is determined by using a where i the number of row and j is number of column in which the element is.
Since 6 is in 2nd column and 2nd row <u>,</u> it's position can be written as a
<u>Comparing with</u> a
4x^3+6x^2-9x+1 is an example
Double then triple both the numerator and denominator
remember any number divide by itself is 1(value will not change)
188/11 x 2/2= 376/22
188/11 x 3/3= 564/33
they all reduce to 188/11= 17.09
hope this helps
