2x+1=6x+2x^2 + 5
The entire right side of the equal sign it is under a radical. I'm pretty sure the answer is x=2 x=-1 I just want confirmation, Thanks

You'd have to square both sides. FOIL the left side. get everything to one side and factor

anonymous · Answer

Yeah, that's what I did

But it's asking for 1 value of x how do I know which one it is? @bibby

bibby · Answer

2x+1(2x+1)

4x^2+4x+1 = 2x^2+6x+5

try the next step on your own

It's 2x^2 - 2x - 4 right?

bibby · Answer

2x^2-2x-4 = 0 yeah

I don't know how to factor that

anonymous · Answer

I was right, I just chose the positive x value, but thanks anyways.
