Answer:
   x ≈ 2.87
Step-by-step explanation:
We  can subtract 6 to put the equation into a form easily solved.
   x^2 +2x +1 = 15
   (x +1)^2 = 15
   x +1 = √15 . . . . . for the greatest solution, we only need the positive root
   x = √15 -1 ≈ 2.87

We have an equation: 2/1= ?/2.25
Cross multiply:
1*?= 2*2.25
⇒ ?= 2*2.25= 4.5
The final answer is 4.5~
