➷ Here are the steps to solving that problem:
(2x+1)^2
=(2x+1)(2x+1)
=(2x)(2x)+(2x)(1)+(1)(2x)+(1)(1)
=4x^2+2x+2x+1
=4x^2+4x+1

Answer:
Option D is correct.
D- A number that cannot be expressed as a fraction, , where p and q are integers
Step-by-step explanation:
Irrational number:
An irrational number can not be expressed as a fraction or ratio of integers, like
where p and q are integers
And also it can not be expressed as terminating decimal or repeating decimal
Example of the irrational number is given below.



Therefore option D (A number that cannot be expressed as a fraction, , where p and q are integers) is correct .
Here, First two number represents Product of first two numbers in L.H.S.
For example, 5 * 3 = 15
Or 9 * 2 = 18
Now, second two numbers represent product of 1st & 3rd number,
For example, 5 * 2 = 10
Or 9 * 4 = 36
Now, Last two numbers represent Sum of 4 digit-number minus middle number.
So, 7 + 2 + 5 = 143547
In short, Your Final Answer would be: 143547
Hope this helps!
