Question

Find discriminant of – x^2+1/2x+1/2=0​

Answer 1

Answer:

– x^2+1/2x+1/2=0​

a = -1

b= 1/2

c= 1/2

discriminant = b^2 - 4ac

                     = (1/2)^2 - 4(-1) (1/2)

                      (1/4) +(4)(2)                          lcm = 4

                         = 1 + 8 / 4

                             = 9/4

Answer 2

Answer:

x²+1/2x+1/2=0

2x²+x+1=0

d=b²-4ac

d=(1)²-4×2×1

d=1-8

therefore d= -7 ans.
