Answer:
See, many people think (p2 + 9) is the square of P + 3. but when u square (p + 3), u get (p^2 + 2*3*p + 9) which is equal to (p^2 + 6p + 9). here we have (p^2 + 9) which is not a square...
we need 6x on that at the middle to factorize it

Step-by-step explanation:
Answer«
(p²+9)
we can write 9 as 3²
(p²+3²)
It is in form of {(a²+b² = (a+b)²-2ab}
a=p and b=3
=(p+3)²-2(p)(3)
= p²+2(p)(3) - 6p
= p² + 6p -6p
both are in different signs so they will cancel
= p²+0
=p²
last we have only p² so we cannot factorize it because it is not an equation
