Answer:
Therefore, the solutions of the quadratic equations are:

The graph is also attached.
Step-by-step explanation:
The solution of the graph could be obtained by finding the x-intercept.

Finding the x-intercept by substituting the value y = 0
so

∵ y = 0












So, when y = 0, then x values are 3, and 5.
Therefore, the solutions of the quadratic equations are:

The graph is also attached. As the graph is a Parabola. It is visible from the graph that the values of y = 0 at x = 5 and x = 3. As the graph is a Parabola.
Answer:
