Question

Discriminant of xsqaure - 1/2x +1/2=0

Answer 1

`\boxed{D = 15/8}`

Explanation:

=>
`x^2-(1)/(2) x +(1)/(2) = 0`

Comparing it with the standard form of quadratic equation
`ax^2+bx+c = 0,` we get

a = 1, b = -1/2 and c = 1/2

Discriminant =
`b^2-4ac`

`D = (-1/2)^3+4(1)(1/2)\\D = -1/8 + 2\\D = (-1+16)/(8) \\D = (15)/(8)`
