Answer:
[tex](6x+5)^{2}[/tex]
Step-by-step explanation:
[tex]36x^{2}+60x+25[/tex]
Just looking at the equation, one can see that the first element ([tex]36x^{2}[/tex]) and the last element ([tex]25[/tex]) are both perfect squares. One can see that when one multiplies the number and then doubles the result, the resulting values will be the value in the middle. Therefore, it is clear that is the answer is;
[tex](6x+5)^2[/tex]
