Rational expression constantsFind, Algebraically, the constants A and B such that 7x-6 / x^2-x-6 = A/x+2 + B/x-3 |

Re: Rational expression constantsWill you post your attempt and/or any ideas you have? |

Re: Rational expression constantsyea sure, here they are: ive tried using (x+2)(x-3) as the denominator and took it out from all 3 then, ax + 3a + bx + 2b = 7x-6 ive tried substituting a and couldnt go any further than this |

Re: Rational expression constantsNow set x = 3 and you get B = 3. Do you see how? |

Re: Rational expression constantsI've tried following your suggestions but couldn't quite get the 3 for B, however what I got was 7x-6 = B by eliminating all the like factors and can you also elaborate on the rules of plugging in the 3 as x. Thanks |

Re: Rational expression constants |

Re: Rational expression constantsalright I see, I just made a small error and forgot to put 5 infront of B. Anyways, thanks for clearing this up. |
