What is the value of n that the expression x^2 + 11x + n is a perfect square trinomial?
a. 11
b. 25
c. 30.25
d. 36
To find the value of n that makes the expression x^2 + 11x + n a perfect square trinomial, we need to take half of the coefficient of x (11/2 = 5.5) and square it (5.5^2 = 30.25).
Therefore, the value of n that makes the expression a perfect square trinomial is c. 30.25.
