2x^(2)+kx+4=0

Determine k for which the roots of the equation 9x^(2)+2kx+4=0 are equal.

Find the value of k so that the sum of the roots of the quadratic equation is equal to the product to the roots : (k+1)x^(2)+2kx+4=0

Find the values of k for which the given quadratic equation has real and distinct roots: (i) kx^(2)+6x+1=0" "(ii)" "x^(2)-kx+9=0 (iii) 9x^(2)+3kx+4=0" "(iv)" "5x^(2)-kx+1=0

Find the value of k for which the given equation has real and equal roots: 2x^(2)-10x+k=09x^(2)+3kx+4=012x^(2)+4kx+3=02x^(2)+3kx+4=02x^(2)-kx+1=0kx^(2)-5x+k=0x^(2)+kx+1=0kx^(2)-5x+k=0x^(2)+k(4x+k-1)+2=0x^(2)-2x(1+3k)+7(x+2k)=0(k+1)x^(2)-2(k-1)x+1=0

If the equations 2x^(2)+kx-5=0 and x^(2)-3x-4=0 have a common root,then the value of k is

4x^(2) + kx - 2 = 0 has no real roots if…..

The equation kx^(2)+x+k=0 and kx^(2)+kx+1=0 have exactly one root in common for

The equation kx^(2)+x+k=0 and kx^(2)+kx+1=0 have exactly one root in common for
