Homework Help: Inter. Algebra

Posted by bobpursley on Sunday, December 3, 2006 at 11:06am.

I find it curious here:
a - b=2 in this case,

rationalize by multplying both sides by a+b, getting
(x+5)/2 = a+b
now add the original equation..
2= a-b
or 2a= 2+ x/2 + 5/2
4sqrt(2x+3)= x+9
square both sides..
16(2x+3)= x^2+18x + 81

square root sign 2x+3 - square root sign x-2 = 2. And the instructions are to solve the equation.
