Graphing allows us to use the x - axis to detect number of solutions and state those solutions.
Question 2
2.
2 solutions
1 solution
No solution
Typically we would try to get x by itself but we have two x terms of different powers so we can't isolate them easily. So it is easiest to make one side zero and graph the quadratic to see where the intercepts are.
Question 3
3.
What does x equal? We need to look at the x - intercepts. The graph value when y is 0 tells us what x is.
Example: x2 + 5x + 4 = 0
Question 4
4.
What does x equal? We need to look at the x - intercepts. The graph value when y is 0 tells us what x is.
