x is either 2 or -1 OpenStudy (anonymous):

i was gonnea say the same OpenStudy (anonymous):

too slow! OpenStudy (anonymous):

hehehehe OpenStudy (anonymous):

my comp is freazing every once in a wile thats y OpenStudy (anonymous):

But 2 or -1 doesn't show :( OpenStudy (anonymous):

square both sides and then rearrange so it gives x^2-x-2=0 then you factorise to give (x-2)(x+1) hence x is 2 or -1 OpenStudy (anonymous):

how old r u btw OpenStudy (anonymous):

I'm 10, I'm a mathematical god OpenStudy (anonymous):

those aren't options OpenStudy (anonymous): OpenStudy (anonymous):

? OpenStudy (anonymous):

Thanks for the help! OpenStudy (anonymous): OpenStudy (anonymous):

Coconutshake, if you square:$\sqrt{x}+14-12=x$,$\sqrt{x}+2=x$wouldnt' you get $x+4=x^{2}$ Therefore the equation$x^{2}-x-4=0$ OpenStudy (anonymous):

ekk that should be $x^{2}-4x+4=0$ OpenStudy (anonymous): OpenStudy (anonymous): OpenStudy (anonymous):

x = -10 and x = -13 is the correct answer OpenStudy (anonymous):

You're actually all incorrect. |dw:1338055044817:dw|
