Answer:Step-by-step explanation:## ✢

Given:-3 is a root of Quadratic Equation x²-2px-6=0.

## ✢

ToFind:-The Value of

p.## ✢

Solution:-p(x)=x²-2px-6=0

Putting ‘x’=3, we get:

⇒ p(3)=(3)²-2p(3)-6=0

⇒ 9-6-6p=0

⇒ 3=6p

∴ The Value of p satisfying this Quadratic Equation is.Answer:p=1/2

Step-by-step explanation:give x=3 is one root of Q.E

q(x)=x^2-2px-6

as x is 3 when

x^2-2px-6=0

when substituting

9-6p-6=0

3=6p

p=1/2
