Answer:
The solutions of the original equation are x=-5 and x=-2
Step-by-step explanation:
we have

Let

Rewrite the equation

Complete the square



rewrite as perfect squares

square root both sides




the solutions are
u=-2,u=1
<em>Alternative Method</em>
The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
the solutions are
u=-2,u=1
<em>Find the solutions of the original equation</em>
For u=-2
----> 
For u=1
----> 
therefore
The solutions of the original equation are
x=-5 and x=-2
