Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ 1 }{ x+5 } + \frac{ x^2 }{ x5 }\] find the common denominator

Best ResponseYou've already chosen the best response.1find common denominator multiply the numerator of first fraction by the denominator of 2nd fraction multiply the numerator of 2nd fraction by the denominator of first fraction here is an example \[\huge\rm \frac{ a } {\color{Red}{ b} }+\frac{ c }{\color{blue}{ d} } =\frac{ a\color{blue}{d}+c\color{Red}{b} }{ bd}\]

Best ResponseYou've already chosen the best response.1hmm that looks wrong when the denominators are not the same to get the common denominator multiply denominators of both fractions just like in the example i gave you

Best ResponseYou've already chosen the best response.1make sense ? or do you need an example with numbers ?

Best ResponseYou've already chosen the best response.1alright i'll give you an example \[\huge\rm \frac{ 2 }{ 3 } +\frac{ 4 }{ 5 }\] denominators aren't the same so i should multiply them 3 times 5 = 15 so 15 is my common denominator \[\frac{ ??? + ?? }{ 15 }\] when we convert two fractions to one we should multiply the numerator of `1st` fraction with the denominator of `2nd` fraction and multiply the numerator of `2nd` fraction with the denominator of first fracton just like cross multiplication but we should keep the positive sign dw:1444600450247:dw

Best ResponseYou've already chosen the best response.1well alright common denominators (x+5)(x5) dw:1444600811171:dw what would you get at the numerator ?

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ x5 +x^2 (x+5) }{(x+5)(x5) }\] (x5) times 1 = x5 distribute parentheses x^2 (x+5)

Best ResponseYou've already chosen the best response.0so it would be x^3 not x^4

Best ResponseYou've already chosen the best response.1that's it now you can foil (x5)(x+5) if you want :=)

Best ResponseYou've already chosen the best response.1but anywyas let's learn how to foil dw:1444601278891:dw write one parentheses at the top of the box and one at left side multiply each left term by the top one
