Question

ਦੋ ਘਾਤੀ ਸਮੀਕਰਣ 2x² – √5x + 1 = 0 ਦੇ : / The quadratic equation 2x²– √5x + 1 = 0 has : *​

Answer 1

Step-by-step explanation:

Given equation is 2x

2

−

5

x+1=0

On comparing with ax

2

+bx+c=0 we get

a=2,b=−

5

and c=1

D=b

2

−4ac

=(−

5

)

2

−4×2×1=5−8

∴ Discriminant =−3<0

Since, discriminant is negative ∴ quadratic equation 2x

2

−

5

x+1=0 has no real roots . i.e, imaginary roots.
