Question

the quadratic equation 2x2-root 5 x +1=0 has

Answer 1

Step-by-step explanation:

Here a = 2, b = -√5 and c = 1

Now we will find discriminant

${b}^{2} - 4ac$

=

${ (- \sqrt{5})}^{2} - 4 \times 2 \times 1$

= 5 - 8

= -3

Since discriminant is less than 0,

Therefore the given quadratic equation has no real roots.
