Answer:
![(2p+9)^2](https://tex.z-dn.net/?f=%282p%2B9%29%5E2)
Step-by-step explanation:
The given expression is
![4p^2+36p+81](https://tex.z-dn.net/?f=4p%5E2%2B36p%2B81)
This is in the form;
![ap^2+bp+c](https://tex.z-dn.net/?f=ap%5E2%2Bbp%2Bc)
![a=4,b=36,c=81](https://tex.z-dn.net/?f=a%3D4%2Cb%3D36%2Cc%3D81)
![ac=4\times 81](https://tex.z-dn.net/?f=ac%3D4%5Ctimes%2081)
Rewrite to get
![ac=4\times 9\times9](https://tex.z-dn.net/?f=ac%3D4%5Ctimes%209%5Ctimes9)
![ac=18\times18](https://tex.z-dn.net/?f=ac%3D18%5Ctimes18)
We split the middle term to obtain;
![=4p^2+18p+18p+81](https://tex.z-dn.net/?f=%3D4p%5E2%2B18p%2B18p%2B81)
Factor to get;
![=2p(2p+9)+9(2p+9)](https://tex.z-dn.net/?f=%3D2p%282p%2B9%29%2B9%282p%2B9%29)
Factor further to get;
![=(2p+9)(2p+9)](https://tex.z-dn.net/?f=%3D%282p%2B9%29%282p%2B9%29)
We simplify further to get;
![=(2p+9)^2](https://tex.z-dn.net/?f=%3D%282p%2B9%29%5E2)
