प्रश्न

Determine the nature of root of the quadratic equation.

\[\sqrt{3} x^2 + \sqrt{2}x - 2\sqrt{3} = 0\]

योग

उत्तर

\[\sqrt{3} x^2 + \sqrt{2}x - 2\sqrt{3} = 0\]

In order to find the nature of the roots we need to find the discriminant.  

D = b2 - 4ac

\[a = \sqrt{3}, b = \sqrt{2}, c = - 2\sqrt{3}\]

\[D = \left( \sqrt{2} \right)^2 - 4 \times \sqrt{3} \times \left( - 2\sqrt{3} \right)\] 

= 2 + 8 (3)

= 2 + 24

= 26 > 0

Since, the D > 0 so, real and unequal root.
