Solve for X
1.
- 2 = 1
Add 2 to both sides:
= 1 + 2
= 3
Multiply both sides by 3
x = 3(3)
x = 9
Check solution in original equation

;
2.
- =
Factor the 3rd denominator
- =
Multiply by the common denominator, namely x(x-2)
x(x-2)* - x(x-2)* = x(x-2)*
Cancel the denominators and you have:
x(x) - (x-2)(x+1) = 8
FOIL
x^2 - (x^2 - x - 2) = 8
Remove the brackets, (change the signs)
x^2 - x^2 + x + 2 = 8
x = 8 - 2
x = 6
:
Check solution of x=6, in the original equation
:
:
3.
Find the square root of both sides
x = +/-
x = +6
and
x = -6
