Answers:
- first blank = 0
- second blank = 1
- third blank = 0
So basically the two solutions are (-2, 0) and (1, 0)
=============================================
Explanation:
In this context, the term "solution" is another word for "x intercept". Also, the term "root" is the same as "x intercept". We have three ways to say the same thing.
The blue graph crosses the x axis at the locations (-2,0) and (1,0); therefore, these are the roots. We can say that x = -2 and x = 1 are the roots as shorthand.
Side note: This is assuming the blue curve crosses the x axis at the midpoint between x = 0 and x = 2.
