Answer:
We can use perfect square trinomial method
Step-by-step explanation:
We can use perfect square trinomial method.
We have the expression x2 + 12x + 36
The first and third term of this expression are perfect square:
Perfect square of x^2 = x
Perfect square of 36 is 6
So we can use the formula:
(a^2+2ab+b^2) =(a+b)^2
For given expression:
(x2 + 12x + 36) = (x+6)^2 ....
