1. Clear fractions using LCD.
LCD=12(x)(x-1)
12(x)(x-1) over x + 12(x)(x-1) = 7(12(x)(x-1)
12(x-1)+12x=7x(x-1)
12x-12+12x=7x^2-7x
24x-12=7x^2-7x
2. Put into quadratic form: ax^2+bx+c=0
7x^2-31x+12=0
(7x-3)(x-4)=0
7x-3=0 or x-4=0
x=3/7 or x=4
3. You could...
factor
complete the square
quadratic form
square root property
*you must show the domain restrictions!
x cannot equal o or 1
I think it's important to know what exactly the LCD is because I wasn't very sure of that until today I got the correct definition. Least Common Denominator[LCD]: is the number or term that can be divided by every denominator in the equation. I hope I may have helped, it helped me. =]
