y = x^2 - 2x + 2
y - 2x = - 2 Step 1: First you have to change this into standard form : Y = MX +B )
+2x +2x
----------------
Y = 2x - 2
2x - 2 = x^2 - 2x +2 Step 2) Substitute this variable into the quadratic equation
-2x +2 -2x+2
---------------------
0 = X^2 -4x +4 Step 3) Solve the quadratic equation
0=(x - 2)(x - 2)
You have to make the equation equal Zero so if it`s positive to make it zero you have to make it negative, so if it`s negative you have to make it Positive.
For example :
0 = (x - 2)
X has to be positive 2
But if it was 0 = (x +2)
X would have to be negative 2
So the value of X is 2 so what you do next is Step 4) Substitute x value into linear equation to get y value
y = 2x- 2 = 2(2)- 2 = 2
Solution = (2,2)
