  • You asked how to do it. Here's how: Essentially the same way you do it with ordinary fractions. If you have (1/2) + (2/3) + (3/4) the first thing you look for is a common denominator. That's a number into which all the common denominators divide into. In my example, 12 would do. In your question you've got a head start because the second denominator is already the product of the first and third so will suit on its own. Then for each fraction you multiply top and bottom by something to make its denominator into the common denominator. In my example 1/2 needs to become 6/12 by multiplying top and bottom by 6. 2/3 needs to become 8/12 by multiplying top and bottom by 4 and 3/4 needs to become 9/12 by multiplying top and bottom by 3. Now add the fractions together (6/12)+(8/12)+(9/12) = (6+8+9)/12 collect the terms on the top = 23/12 Then, look for common factors between numerator and denominator to see if the fraction will cancel. Divide top and bottom by this factor to complete the simplification. (I didn't have one, but yours will).
  • (4x+8+2) over (3x-4 +3x^2-4x+x) then simplify again: 4x+10 3x²-4
  • Better done with paint!
  • I think I just became a little dumber inside.
  • =(4x^2+8+6x-8)/(3x^2-4x) =(4x^2-6x)/(3x^2-4x) =(4x-6)/(3x-4) that's the answer..Ü
