Question

7. Find value of 'm’so equation x2 + m (4x + m – 1) + 2 = 0 has equal roots.
8. Find the value of 'p' so that px(x – 3) + 9 = 0 has equal roots.
9. If x = 2 is a root of the equation 3x2 + 7x + p = 0, find the value of 'k’so
that the roots of the equationx2 + k(4x + k – 1) + p = 0 are equal.
10. If the roots of the equation (a - b)x² + (b - c)x + (C – a) = 0 are equal,
then P.T 2a = b + c​
