Question 217912: For this problem I have to simplify. I have tried it several times and so not understand it.
(v-7/v-9)-(v+1/v+9)+(v-45/v^2-81)=
Please help me to solve this. I really would appreciate it. Thanks

(v-7/v-9)-(v+1/v+9)+(v-45/v^2-81)
IF you mean:
(v-7)/(v-9)-(v+1)/(v+9)+(v-45)/(v^2-81) then:
(v-7)/(v-9)-(v+1)/(v+9)+(V-45)/(V+9)(V-9) FACTOR THE LAST DENOMINATOR.
[(V-7)(V+9)-(V-1)(V-9)+(V-45)]/(V+9)(V-9) EXPAND THE FIRST BTWO NUMERATORS.
(V^2+2V-63-V^2+10V-9+V-45)/(V+9)(V-9) COMBINE KIKE TERMS IN THE NUMERATOR.
(13V-117)/(V+9)(V-9)
13(V-9)/(V+9(V-9) CANCEL OUT THE (V-9) TERMS.
13/(V+9) ANS.
