the directions go as follows:
perform the following operations and then simplify.
---2----------2
2x + 3x----x - 3x + 21----x+7
______-_________-_____
------------2
----------x - 2x - 63
that is 2x squared + 3x - x squared + 3x + 21 - x-7
over
x squared - 2x - 63

that is the problem, x equals x. and I am sorry, I do not kow how to write problems that way on this site, it moves things around so yes bingo bet and mr p. have it correct as far as the problem goes, but the answer is (x-2)/(x-9), that is the asnwer in the back of the book, but I want to know how they got that answer. thank you

The answer simplyfied is...
(x+2)(x+7) / (x+9) (x-7)
Just simplify the numerator and factor the numerator and the denominator.

(2x² + 3x - x² - 3x + 21 - x - 7) / (x² - 2x - 63) =
(x² - x + 14) / (x² - 2x - 63) =
{(x + ½(1 - i√55))(x + ½(1 + i√55))} / {(x + 2 - i√62)(x + 2 + i√62)}

A=a million/2bh start up via multiplying a million/2's reciprocal (opposite=2, turn the numbers) then divide each little thing via 2: 2A=bh (the a million/2 is canceled) to detect b divide each little thing via h and you get: 2A/h=b

didyou mean ((2x^2 + 3x) - (x^2 -3x + 21) - (x - 7))/(x^2 - 2x - 63)

geez i have a hard time reading this please update it
pls use ( ) and ^
anyway do you mean
(2x^2+(3x-x)^2+21-x-7)/(x^2-2x-63)
