Which graph can be used to find the solution(s) to x2 - 4x + 4 = 2x - 1 - x2?
Solution:
Given x2 - 4x + 4 = 2x - 1 - x2
⇒ Sorting like terms,
x2 + x2 - 4x - 2x + 4 +1 = 0
2x2 - 6x + 5 = 0
The quadratic graph can be used to find the solution(s).
From the graph, we see that it doesn’t cut the x-axis at all. Thus we can infer that no real solution exists for the given quadratic expression.

Summary:
To find the solution(s) to x2 - 4x + 4 = 2x - 1 - x2 ⇒ 2x2 - 6x + 5 = 0, a quadratic graph can be used. As the graph doesn’t cut the x-axis, we can infer that no real solution exists for the given quadratic expression.
