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

1 answer:
Answer:-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
