Answer:
1. x + 5 = 7
2. x² - 3√x + 2 = 0
3. x + y = 10
Step-by-step explanation:
they all are not a quadratic equation. because any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power solve for x in the quadratic equation x² + 4x + 4 = 0.
