Answer:
A only.
Step-by-step explanation:
A. 2^2 + 3(2) - 10 = 0
4 + 6 - 10 = 0
10 - 10 = 0
0 = 0 (correct)
-5^2 + 3(-5) - 10 = 0
25 + (-15) - 10 = 0
B. 2^2 - 3(2) - 10 = 0
4 - 6 - 10 = 0
-2 - 10 = 0
-12 = 0 (not correct)
-5^2 - 3(-5) - 10 = 0
25 - (-15) - 10 = 0
40 - 10 = 0
30 = 0 (not correct)
C. 2^2 + 7(2) + 10 = 0
4 + 14 + 10 = 0
18 + 10 = 0
28 = 0 (not correct)
-5^2 + 7(-5) + 10 = 0
25 + (-35) + 10 = 0
-10 + 10 = 0
D. 2^2 - 7(2) + 10 = 0
4 - 14 + 10 = 0
-5^2 - 7(-5) + 10 = 0
25 - (-35) + 10 = 0
60 + 10 = 0
70 = 0 (not correct)
