Solve the equation by finding square roots.
9x^2+12x+4=5

anonymous · Answer

subtract the 5 so you get -1 
9x^2+12x-1=0 *can't factor so quadratic equation* $$-12\sqrt{12^2 -4(9)(-1)}/2(9)$$ 
solve the rest

anonymous · Answer

We've never done it like that before in class, so I'm honestly lost.

anonymous · Answer

what do you do in class

anonymous · Answer

We normally would do something like subtract the 4 and get 1 on the other side, then figure out (#x+#)^2 = 5 then solve from there, but I'm not exactly sure how to get the two numbers I substituted with #.

anonymous · Answer

I'm really not sure, this is all completely new to me.

anonymous · Answer

(#x+#)^@ = 1, I mean, but tbh I don't really know what I'm saying at all now

anonymous · Answer

you can try this since i have no idea what you wrote

anonymous · Answer

I have no idea what you wrote either, so hopefully there will be someone else that learned the useless way I did.........
