x=1 or 1.25

Explanation:

As we clearly see that factorisation is difficult so I suggest we use the quadratic formula for this.

The quadratic formula states that for an equation of the form ax2+bx+c=0, the value of x can be calculated as

x=b±b24ac2a

Comparing this with your question
x=n
a=4
b=-9
c=5

Plug in these values and find the values of n.
