Question

find the discriminant of the equation 2 x square - 5 x minus 3 equals to zero find and hence find the nature of its roots find them if they are real

Answer 1

Answer:

The roots are real and distinct

Step-by-step explanation:

Discriminant=b2-4ac

a=2,b=-5,c=-3

=b2-4ac

=-5whole square-4×2×-3

=25+24

=49

The nature of the roots are real and distinct

By factorization method

2x2-5x-3

2x2-6x+1x-3

2x(x-3)+1(x-3)

2x+1=0,x-3=0

x=-1/2,x=3

I hope this answer may help you
