Answer:
1. a = 1, b = -5, c = 4
Discriminant: (-5)² – 4 (1) (4) = 25 – 16 = 9
Nature of the Roots: real, distinct, rational
2. a = 2, b = -4, c = -1
Discriminant: (-4)² – 4 (2) (-1) = 16 – -8 = 24
Nature of the Roots: real, unequal, irrational
3. a = 2, b = -8, c = 0
Discriminant: (-8)² – 4 (2) (0) = 64 – 0 = 64
4. a = 1, b = 2, c = 3
Discriminant: (2)² – 4 (1) (3) = 4 – 12 = -8
5. a = 1, b = -1, c = 2
Discriminant: (-1)² – 4 (1) (2) = 1 – 8 = -7
That's the answer! I'm also a grade 9 student. kakatapos lang din namin ang discriminant last week hehe. hope it helps :). Pa-brainliest ty.
