If the roots of `x^(2)-2(7+3m)x+55m+45=0` are equal,then m

p, q, r and s are integers. If the A.M. of the roots of x^(2) - px + q^(2) = 0 and G.M. of the roots of x^(2) - rx + s^(2) = 0 are equal, then

If the roots of the equaton x^(2)-10x+21=m are equal then m is-

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

If A.M of the roots of x^(2)-2ax+b^(2)=0 is equal to the ......... of the roots of the equation x^(2)-2bx+a^(2)=0

If both roots of the equation x^(2)-(m+1)x+(m+4)=0 are negative then m equals

If the product of the roots of 5x^(2)-4x+2+m(4x^(2)-2x-1)=0 is 3, then m=

The roots of the equation x^(2)-10x+21=0 are equal the m is
