Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
The square of the sum of 7 times x and 3 divided by 4 times the difference of x and 1.
The square of the sum of 7 times x and 3 would be written as
[tex](7x+3)^2[/tex]
and 4 times the difference of x and 1 is written as
[tex]4(x-1)[/tex]
Mathematically, it is expressed as
[tex]\dfrac{(7x+3)^2}{4(x-1)}[/tex]
Hence, Third option is correct.
