Question

Help 8+x2=−12..im confused

Answer 1

Answer and Explanation

__________________________________________________________

-10

__________________________________________________________

The answer is -10 because...

You need to multiply 2 by "x," and to find out what "x" is, we need to add...

`2+-12`

__________________________________________________________

And if we add
`2` by
`-12`, we get
`-10`, which is our answer.

__________________________________________________________

and now, if we add
`-20` by
`8`, we get
`-12`, which is what the equation equals, and this is how we know it is correct.

Hope this helps! :)

Answer 2

Explanation:

No real solutions exist. Subtract 8 on both sides to get:

`x^2=-20`

You cannot take the square root of a negative number without involving imaginary numbers.
