Answer:
See below
Step-by-step explanation:
- See attached for missing part of the question
1. Which of the given mathematical sentences are quadratic equations?
- x^2 + 9x + 20 = 0
- 15 - 6h^2 = 10
- 4x^2 - 25 = 0
- m^2 = 6m - 7
The rest are quadratic inequalities
2. How do you describe quadratic equation?
- They are polynomials of one variable, second degree and have equation sign
3. How would you describe those mathematical sentences which are not
quadratic equations?
4. How are they different from those mathematical sentences which are not
quadratic equations?
- Equations have 2 roots as solution; have equation sign (=)
- Inequalities have intervals as solution; have inequality sign (>, <, ≥, ≤)
