Question

If-5 is a root of the quadratic equation 2x + px -15 = 0 and the quadratic equation
px + x+ k = 0 has equal roots, find the value of k.​

Answer 1

Answer:

K = 30

P = 5

Here . x = -5

So keeping the value of x in eq. 1 we will get the value of P

And then keeping the value of P and X in eq. 2 will give you the value of K
