Answer:
1. a= 1 b= -4 c= -12
discriminant 16-4(1)(-12)= 64
Nature of Roots Real Rational Unequal
2. a= 1b= 0 c= -16
discriminant 0-4(1)(-16)=64
Nature of Roots Real Rational Unequal
3. a= 1 b= 4 c=4
discriminant 16-4(1)(4)= 0
Nature of Roots Real Rational Equal
4. a= 3 b= -2 c= 1
Discriminant 4-4(3)(1)= -8
