Question

3xsquare-5x+k=0 has equal roots

Answer 1

=>> answer

k = 25/12

=>> to find

value of k

=>> explanation

3x^2 - 5k + k =0 has equal roots

for equal roots = d = 0

d = b^2 - 4ac =0

(-5)^2 - 4(3)(k) = 0

25 - 12 k = 0

k = 25/12

related formula

1 ) = d > 0 = roots are real and unequal.

2 ) = d = 0 = roots are real and equal

3 ) = d < 0 = roots are imaginary
