Answer:
value of n is 36
Step-by-step explanation:
\(x^2+12x+n\)
To make perfect square trinominal , apply completing the square method
Take the coefficient of middle term, divide by 2 and square it
then add the square to make perfect square
\(x^2+12x+n\)
12 divide by 2 is 6
square of 6 is 36
Now add 36 to make perfect square
\(x^2+12x+36\)
\((x+6)(x+6)\)
\((x+6)^2\)
