State whether `k` is the root of the given equation `y^2-(k-4)y-4k = 0 `

State whether x=(-k)/(2) is root of the quadratic equation 2x^(2)+(k-6)x-3k=0 .

For what value of k, -2 is a root of the equation 3x^(2)+4x+2k=0 ?

If -2 is a root of the equation 3x^(2)+7x+p=0, find the value of k so that the roots of the equation x^(2)+k(4x+k-1)+p=0 are equal.

If the roots of the quadratic equation x^(2)-2kx+2k^(2)-4=0 are real,then the range of the values of k is

The following equations have equal roots find k in each equation. k^2x^2 - 2(2k – 1) x + 4 =0 .

For what values of k, the equation x^2+2(k-4) x + 2k=0 has equal roots?

The value of k for which the pair of linear equation 4x+6y-1=0a n d2x+k y-7=0 represent parallel lines is (a) k=3 (b) k=2 (c) k=4 (d) k=-2

Sum of the roots of a quadratic equation is double their product. Find k if equation is x^(2)-4kx+k+3=0 .

Sum of the roots of a quadratic equation is double their product. Find k if equation is x^(2)-4kx+k+3=0 .
