hi guys

i need to find the equation of the tangent at a certain point in the curve

the point it (1,2)

the equation is y=

now here is what i have so far.

m =

m =

from that point i get lost. im assuming i have to multiply by the conjugate but i think im screwing something up when i do that.

If someone could do that with the inbetween steps I would appreciate it.

Also, teach me how to put things under a square root in the math tags XD

thanks

dont answer llawll i was factoring out nonexistent termx XD
