Homework Statement
1)
____1___ __ ___2___ __ ____3____ =0
3x-7 5x-5 3x+1
here's the other way of presenting the problem.
1/(3x-7) - 2/(5x-5) - 3/(3x+1) =0
ans: x=2/3, 3
2) _____2_____ + _____1_____ __ _____1_____ =0
(x^2-36)^1/2 (x+6)^1/2 (x-6)^1/2
2/sqrt(x^2-36) + 1/sqrt(x+6) - 1/sqrt(x-6) =0
ans:x=10
3) (x+7)^1/2 - (x+2)^1/2 = (x-1)^1/2 - (x-2)^1/2
ans:x=2
Homework Equations
The Attempt at a Solution
on problem #3, i tried squaring both side of the equations to cancel out those sqrt root but im thinking im doing it the wrong way because the solution is way too long.
