If `-5` is a root of the quadratic equation `2x^2+p x-15=0` and the quadratic equation `p(x^2+x)+k=0` has equal roots, find the value of `kdot`

Text Solution

Verified by Experts

Given -5 is a root of the quadratic equation `2 x^{2}+p x-15=0.`
therefore-5 satisfies the given equation.
therefore` 2(5)^{2}+p(-5)-15= `
therefore 50-5 p-15=0
therefore 35-5 p=0
therefore 5 p=35=p=7
