constant​

Answer 1

Answer:

hi good morning dear .. can we friend s ..........

Answer 2

Answer:

hello bro here is your answer

Given: equation x

2

−3x−m(m+3)=0, where m is a constant

To find the roots of the equation

Sol: the given equation is of form ax

2

+bx+c=0∴a=1,b=−3,c=−m(m+3)

We know the roots of the equation can be find out using the formula,

x=

2a

−b±

b

2

−4ac

Substituting the values of a, b, c, we get

x=

2

−(−3)±

(−3)

2

−4(1)(−m(m+3)

⟹x=

2

3±

9+4m

2

+12m

⟹x=

2

3±(2m+3)

or x=

2

3+(2m+3)

,x=

2

3−(2m+3)

⟹x=m+3,x=−m are the required roots of the equation

I HOPE ITS HELPFUL FOR YOU
