Answer:
1. 73, irrational and unequal
2.-23, not real numbers
3.89, irrational numbers
4.-48, not real numbers
Step-by-step explanation:
The formula is b²-4ac.
1. a=3 b=7 c= -2
7²-4(3)(-2) = 73.
2. a=2 b=7 c=9
7²-4(2)(9) = -23
3. a=1 b=7 c= -10
7²-4(1)(-10) = 89
4. a=1 b=6 c=21
7²4(1)(21) = -48
ps. there maybe some errors so please review my answer.
