• This Question is Open
1. Rosy95

$\sqrt{x+10}=x-2$ Is this the equation? Are you looking for the value of x?

2. js64

yes

3. hartnn

the first step is to square both sides,

4. Rosy95

$\sqrt{x+10}=x-2$ $(\sqrt{x+10})^2=(x-2)^2$ $x+10=x^2+4$ $x+6=x^2$ You should be able to solve the rest now

5. hartnn

$(x-2)^2=x^2-4x+4$

6. hartnn

$x+10 = x^2-4x+4$

7. js64

k

8. Rosy95

Yes sorry misread that hartnn has the last step

9. Rosy95

so then you get $x-6=x^2-4x$ and solve from there

10. hartnn

$x+6=x^2-4x$

11. hartnn

$x^2-5x-6=0$ can you solve this quadratic ?
