IF the roots of ` x^2-2(5 + 2k ) x+ 3 (7+10k) ` are equal then k=

If the sum of the roots of the Q.E. 3x^(2) + (2k + 1) x - (k + 5) = 0 is equal to the product of the roots, then the value of k is

If k in R , then roots of (x - 2) (x - 3) = k^2 are always

If roots of 7x^(2) - 11 x + k = 0, k ne 0 are reciprocal of each other, then k is equal to

If the product of the roots of the equation x^(2) - 3kx + 2e^(2 log k) - 1 = 0 is 7, then the roots of the equation are real for k equal to :

The following equations have equal roots find k in each equation. x^2 - 2(5 + 2k) x + 3(7 + 10k) = 0 .

If the equation x^(2) + 2 (k+3) x +12k=0 has equal roots, then k=

If the equation x^(2) + 2 (1 + k ļx +k^(2)) = 0 has equal roots, then what is the value of k?

If the sum of the roots of the equation x^2-(k+6)x+2(2k-1)=0 is equal to half of their product, then k= (a) 6 (b) 7 (c) 1 (d) 5
