1. anonymous

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

2. anonymous

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

3. anonymous

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

4. anonymous

but its radical expression though o:

5. anonymous

first square both the sides

6. anonymous

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

7. anonymous

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