Option a. 1/4 is the right answer
Step-by-step explanation:
Given expression is:
[tex]x^2+x[/tex]
Here
we know that
a = x
In order to find the number which should be added
comparing with the formula
[tex](a+b)^2 = a^2+2ab+b^2[/tex]
[tex]2ab = x\\2.x.b = x\\b=\frac{x}{2x}\\b = \frac{1}{2}[/tex]
So, we will add the square of 1/2 which is 1/4
Hence,
Option a. 1/4 is the right answer
