If the equation ` x^2 -2mx+7m-12 =0` has equal roots then m=

If the quadratic equation mx^2+2x+m=0 has two equal roots, then the values of m are

For what values of m will the equation x^(2)-2mx+7m-12=0 have (i) equal roots, (ii) reciprocal roots ?

If the equation x^(2)-15-m(2x-8)=0 has equal roots find the values of m

If the equation x ^(2) - 15 - m ( 2x-8) =0 has equal roots, find the value of 'm'.

If the quadratic equation mx^(2)+2x+m=0 has two equal roots, find m?

If the equation mx^(2)+mx+1=-4x^(2)-x has equal roots, then the values of m are

Find the values of m for which the equation x^2 -2 (5 + 2m) x+ 3 (7+ 10m) =0 has equal roots.
