Question

14. Find the zeroes if the polynomial x2-3x - m (m + 3).​

Answer 1

Step-by-step explanation:

$\huge{ \purple{b}r\red{a} \green{i} \pink{n} \orange{l} \purple{i} \green{s}t}</p><p> \\ \\ </p><p> \huge{ \purple{p}\red{l} \green{e} \pink{a} \orange{s} \purple{e} }$

Let f(x)=x²-3x-m(m+3)

Putting x=-m in f(x)

Now let's check

f(-m)=(-m)²-3(-m)-m(m+3)

=m²+3m-m²-3m

=0

Hence,the zeroes of the polynomial is -m

Answer 2
