Can this be solved algebraically? I'm not looking for a solution, just a simple yes or no.

>> No.4231770

there's no equation bro

>> No.4231793

Yes. Set x = 9 + u
(sqrt(x+16) - 4)/u = 4(sqrt(1+u/16) -1)/u =4(1 + u/32 - 1 + o(u))/u -> 1/8 as u ->0.

Multiply it by a/a, where a is sqrt(x+7)+4.
the x-9 goes away.
