Question

Find the discriminant of an equation x square minus 3 root 5 x minus 2 root 3 is equals to zero check whether the roots are real and if real find the roots?​

Answer 1

Answer:

discriminant of an equation = b^2-4ac

here a= 1, b= -3√5 ,c= -2√3

b^2-4ac = (-3√5)^2 - 4*1*(-2√3)

=45+8√3

= positive

therefore, the roots are real and unequal
