Step-by-step explanation:
Let's solve x^2 - 2x + 2 = 0 using "completing the square:"
1. Take the coefficient of x: It is -2.
2. Halve this, obtaining -1.
3. Square this result, obtaining 1.
4. Add 1, and then subtract 1, between -2x + 2:
x^2 - 2x + 1 - 1 + 2 = 0
5. Rewrite x^2 - 2x + 1 + 1 = 0 beginning with the square of a binomial
(x - 1)^2 + 1 = 0, or (x - 1)^2 = -1
6. Take the square root of both sides, obtaining x - 1 = ±i, or x = 1 ±i
7. Write out the roots: they are x = 1 + i and x = 1 - i (two complex, different roots). No real roots, so the last command of this question is irrelevant. The graph never touches the x-axis; the graph is in Quadrants I and II and is that of a parabola that opens up.

Answer: 
Step-by-step explanation:
Given a System of linear equations, the solution of the system is the point 
in which the lines intersect, where "x" is the x-coordinate and "y" is the y-coordinate.
Having the following System of equations:
You can use the Elimination method to find the value of "x":
-Multiply the second equation by 3.
- Add the equations.
- Solve for "x".
Then, you get:
