Find the roots of the equation x2 – 3x – m (m + 3) = 0, where m is a constant.

-m or m+3

Step-by-step explanation:

Applying difference of two squares

⇒()=(x+m)(x-m)

Substituting this for ()

Factorising -3x-3m=-3(x+m)

(x+m)(x-m)-3(x+m)=0

since we have double (x+m),we'll pick one

⇒(x+m)=0

or (x-m-3)=0

⇒x=-m or x= m+3
