I can't figure out this problem the instructions say: "add or subtract each of the following"

Answer 1

Hi,

since these fractions already have a common denominator, just subtract their numerators.

x^2 - 7x - 8 - (1) = x^2 - 7x - 9

This is still over the common denominator to give an answer of:

x^2 - 7x - 9
-----------------
x^2 + 4x + 3


I hope that helps!! :-))

Answer 2

you have to oh, i dont remember all the word im on summer break. but i get the like terms tagether or w/e so the two "x" squared cross out. then -7x and 4x can go tagether. oh i did this so long ago but as far that i got is ''-3x-8over3, minus 1over x^2+4x=3".... im sorry thats probally not much help. but this is an uber easy problem and i just cant remember :/ try looking at your notes

Answer 3

x² - 7x - 8 . . . . . . . 1
- - - - - - - - ... - ... - - - -- - - -- - =
x² + 4x + 3. . . . x² + 4x + 3

The denominators are the same

x² - 7x - 8 - 1
- - - - - - - - - - =
x² + 4x + 3

x² - 7x - 9
- - - - - - - -
x² + 4x + 3

- - - - - - - -s-
