Answer:
x = 8
Step-by-step explanation:
Step 1: Write an equation
2x - 9 = 7
Step 2: Use the Addition Property of Equality
2x = 16
Step 3: Use the Division Property of Equality
x = 8
value of x is: x= i and x= -i
Step-by-step explanation:
We need to find the value of x from
using quadratic formula.
The term is: 
The quadratic formula is:

Where a = 1, b=0,c=1
Putting values:

So, value of x is: x= i and x= -i
