Question number 1
sqrt (4r + 13) = 2r - 1
I raise each side to the 2nd power and get
4r + 13 = (2r)^2 + 1
Assuming this is right, I simplify it to
(2r)^2 - 4r - 12 = 0
Still assuming I didnt screw up, I'm not sure what to do next or if this is even solvable.
Thanks in advance for any help. I'll post some of the other questions after this one is answered and if I can't figure them out.
