Question

Find the zeroes of the polynomial x² + 3x – m(m+1) ​

Answer 1

Let f(x)=x

2

−3x−m(m+3)

Above polynomial can be written as,

f(x)=x

2

−(m+3)x+mx−m(m+3)

=x(x−m−3)+3(x−m−3)

=(x−m−3)(x+m)

To find the zeroes of f(x), put f(x)=0

(x−m−3)(x+m)=0

x−m−3=0 or x=−m

Required zeros are (m+3),−m
