Answer:
x ² + 36 x + 324
take down the factors of 324 such that multiplication be 324 and addition of that two numbers be 36
so that two numbers are 18 x and 18x
because multiplication of 18 and 18 = 324
and addition of 18x + 18x = 36x
x² + 18x + 18x + 324
= x( x + 18 ) + 18 ( x+ 18 )
take commons = (x + 18) (x + 18 )
hope it help you

X^2-36x+324
(X^2-18x)-(18x+324)
x(x-18)-18(x-18)
(x-18) (x-18)=0
X=18. X=18
(X^2-18x)-(18x+324)
x(x-18)-18(x-18)
(x-18) (x-18)=0
X=18. X=18
