Find all solutions to the equation. -\dfrac{2}{x(x+2)}=\dfrac{x+3}{x+2}− x(x+2) 2 ​ = x+2 x+3 ​ minus, start fraction, 2, divide
Gnoma [55]

Answer:

x=-1

Step-by-step explanation:

We have been given an equation \frac{-2}{x(x+2)}=\frac{x+3}{x+2}. We are asked to find the solutions of our given equation.

First of all, we will cross multiply our given equation as:

-2(x+2)=x(x+2)(x+3)

Subtract x(x+2)(x+3) from both sides:

-2(x+2)-x(x+2)(x+3)=x(x+2)(x+3)-x(x+2)(x+3)

-2(x+2)-x(x+2)(x+3)=0

Now we will factor out (x+2).

(x+2)(-2-x(x+3))=0

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

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

Now we will factor by splitting the middle term.

-(x+2)(x^2+2x+x+2)=0

-(x+2)(x+2)(x+1)=0

-(x+2)^2(x+1)=0

Now we will use zero product property and solve for x as:

-(x+2)^2=0,(x+1)=0

(x+2)=0,(x+1)=0

x=-2,x=-1

Now, we will check for extraneous solutions.

We can see that x=-2 will make both denominators zero because our function is not defined at  x=-2.

Therefore, the solution for our given equation is x=-1.
