Best ResponseYou've already chosen the best response.0This is tricky... you need to know this fact. 2  y = (y  2) you can always flip numbers around a  sign and multiply by a  so 5  x = (x  5)

Best ResponseYou've already chosen the best response.0In this case you want the 2  y to be y  2 because you need a common denominator. so you turn the bottom in to y  2 and then you put a  sign out in front... In this case that negative sign out front would turn your problem into a + sign y/y2 + 8 + y/y  2 Now you have common denominators y + 8 + y  y  2 2y + 8  y  2

Best ResponseYou've already chosen the best response.0i dont understand how you get the common denom....

Best ResponseYou've already chosen the best response.0Well... y  2 and 2  y are opposites of each other.... you should be able to see that if you flip the one on the right around the minus sign it becomes the y  2 ex. 2  y flips to y  2 OK?

Best ResponseYou've already chosen the best response.0then you have to change the subtraction to addition??

anonymous

Best ResponseYou've already chosen the best response.0Yes... because it is the opposite you have to put a  sign out in front, and actually you change the sign of the problem... so in this case the subtraction becomes addition. This is a hard concept.

Best ResponseYou've already chosen the best response.0Then you have a common denominator... so if you look above to my steps you will see that you put everything on the top over y  2 because you now have a common denominator

anonymous

Best ResponseYou've already chosen the best response.07 6 3      T  2 T^2  2T T T  2 factors into (T  2) T^2  2T factors into T(T  2) T factors into T Common denominator is T(T  2) or T^2  2T easier if you write it T(T  2)

Best ResponseYou've already chosen the best response.0The  sign goes with the 3 so it is actually 3(T  2) and 3 * 2 = +6

anonymous

Best ResponseYou've already chosen the best response.0I wish they did cancel... they usually do.. but not here a (x  1) can ONLY cancel with an (x  1) and a (x + 1) can ONLY cancel with (x + 1) Usually you CAN cancel, but not in this problem. You would multiply the numerators (FOIL METHOD) then multiply the denominators (FOIL METHOD) and you would have your answer

anonymous

Best ResponseYou've already chosen the best response.0yes square root both sides

anonymous

Best ResponseYou've already chosen the best response.0Good... so in this problem you have (something)^2 = 27 so you square root both sides

anonymous

Best ResponseYou've already chosen the best response.0(4x  7)^2 = 27 4x  7 = sqrt(27)

anonymous

Best ResponseYou've already chosen the best response.0ok hold on lemme take all that in

anonymous

Best ResponseYou've already chosen the best response.0yes we have to factor all four... but it is difficult to factor when there is a negative in front of the x^2 so for the first fraction in the numerator we are going to factor out a  sign first.  (2x^2  3x  9)

Best ResponseYou've already chosen the best response.0Yes... now cancel anything in ( )'s with like ( )'s Anything on the top with anything on the bottom that matches.

anonymous

Best ResponseYou've already chosen the best response.0close you still have that  sign on top (x  3)  x(x  4) they may want it like x + 3  x^2  4x it is all the same...

Best ResponseYou've already chosen the best response.0Now you also said you had to tell restrictions.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0OK... go back to the factored fractions. The rule is you can NEVER divide by 0 so whatever makes those ( )'s 0 would be a restriction.

anonymous

Best ResponseYou've already chosen the best response.0When you have 4 terms you should try this first. Take the first two terms and take out a common factor. x^3 + x^2 = x^2(x + 1) Take the last two terms and do the same thing. 9x  9 = 9(x + 1) OK?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0x+1 is the answer right?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0OK.. Now you have x^2(x + 1)  9(x + 1) ... good amozing. because (x + 1) is a common factor you now have (x + 1)(x^2  9) BUT this is the difference of two squares. (x + 1)(x + 3)(x  3)

anonymous

Best ResponseYou've already chosen the best response.0So you have the top which is (x + 3)(x  3)  (x + 1)(x + 3)(x  3) then cancel and you are left with 1  x + 1 with restrictions of x cannot be 1,3 or 3
