Question

Find the zeroes of polynomial x2-3x-m(m+3)

Answer 1

Answer:

m^-3m

Step-by-step explanation:

p(x)=x^-3x-m(m+3)

p(0)=0^-(3×0)-m^-3m

=-m^-3m

Answer 2

The zeros of the polynomial are $x=m+3,-m$.

Step-by-step explanation:

Given : Polynomial $x^2-3x-m(m+3)$.

To find : The zeros of the polynomial ?

Solution :

To get the zeros of polynomial is equating to zero,

$x^2- 3x - m( m+3 ) = 0$

Applying middle term split,

$x^2+ mx - ( m+3 )x - m( m+3 ) = 0$

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

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

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

$x= m+3,x=-m$

Therefore, the zeros of the polynomial are $x=m+3,-m$.
