Question

Q.8 State whether the
quadratic equations have two
distinct real roots.Justify your
answer x^2 - 3x + 4 = 0
(a) Yes, because discriminant 7>0
(b) Yes, because discriminant 17>0 (c) No, because discriminant -17>0
(d) No, because discriminant -7>0​

Answer 1

Answer:

No, because discriminant -7<0​

Step-by-step explanation:

x^2 - 3x + 4 = 0

d= b^2-4ac

b=-3  a=1  c=4

d= (-3)^2-4(1)(4)

  = 9-16

  = -7

No, because discriminant -7<0​
