What is the solution (not answer) to (not too) x^2 - 3x + 5 = 0?
This is a quadratic equation. Two possible approches to solving it are
1) quadratic formula, and
2) completing the square.
Let's use the quadratic formula:
a=1, b= -3, c = 5
Then
-(-3) plus or minus sqrt( [-3]^2 - 4(1)(5) )
x = --------------------------------------------------------
2
3 plus or minus sqrt(9-20) 3 plus or minus i*sqrt(11)
= ------------------------------------- = ------------------------------------
2
Please note: These are complex roots, due to the " i ".

Step-by-step explanation:
Answer:
y = 600x + 3659
Step-by-step explanation:
General form of the linear equation:
y = mx + b
Given :
x = 0 represents 1992
x = 0 , y = 3659
So, x value for 1997 becomes:
x = 1997-1992 = 5
at x = 5, y = 6659
Plugging in x = 0, y = 3659 in y = mx+b
3659 = m(0) + b
b = 3659
Plugging in x = 5, y = 6659 and b = 3659
6659 = m(5) + 3659
Solving for m:
m(5) = 6659-3659
5m = 3000
m = 3000/5 = 600
Now plug in the values of unknowns m and b in general equation:
y = 600x + 3659
