X2-81 b2-49 = 0
3c2_75 = 0
1. Compare the three equations and make a statement to describe them.

Check explanation

Explanation:

a. X² - 81

X² - 81 = 0

X² = 0 + 81

X² = 81

X = ✓81

X = 9

b. b² - 49 = 0

b² = 49 + 0

b² = 49

b = ✓49

b = 7

c. 3c² - 75 = 0

3c² = 75

c² = 75/3

c² = 25

c = ✓25

c = 5

The three statements are identical as the value of the letter assigned can be gotten by finding their square roots.
