## ikoreanx3 2 years ago Could anyone show me the steps on how to solve this problem? square root x^2+12x+3=-x

1. ikoreanx3

I got x=-1/4 is this right?

2. ikoreanx3

$\sqrt{x^2+12x+3}=-x$

3. erica.d

$\frac{ -b \pm \sqrt {b^2-4ac }}{ 2a }$

4. ikoreanx3

but its radical expression though o:

5. erica.d

first square both the sides

6. ikoreanx3

I dont understand that part but i know you plug the numbers into the formula. Sorry T: i'm confused.

7. erica.d

squaring both sides will give you x^2+12x+3=x^2 12x=-3 x= -3/12=-1/4
