Question

Please help me!?
What is the solution of x^2+6x=-5?

Answer 1

First, add 5 to both sides of the equation.
Now it becomes x^2+6x+5=0

Now factor this equation.

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

The answer is therefore x=-2,-3

Answer 2

Well My problem says x^2+6x=-5 and its multiple choice.
1) -6
2) -1
3) 1
4)6

Answer 3

Oops! I just woke up, I totally factored that wrong.

It is (x+1)(x+5), so x = -1,-5

Pick 2)
