Step-by-step explanation:

sorry can't find it

Answer 2

Answer:

We know that if m and n are the roots of a quadratic equation ax

2+bx+c=0, the sum of the roots is m+n=− ab

and the product of the roots is mn= ac

.

Let m and n be the roots of the given quadratic equation x

2

+px+q=0. It is given that one of the root is three times the other, therefore,m+n=− ab=− 1p=−p

⇒m+n=−p

⇒3n+n=−p

⇒4n=−p

⇒n=− 4p
