how do you subtract this "(3x+1)

OpenStudy (anonymous):

-(3x+1) or -3x -1

OpenStudy (anonymous):

um can you do both?

OpenStudy (anonymous):

what are you subtracting it from? helps to see the whole problem

2. Explain in complete sentences and demonstrate how to add: My rational expression added to the expression "(3x+1)" can be performed in a very simple way, using a theorem called 'common denominator' and using the invisible numbers we don't see in all the equations. under the expression '(3x+5)' there exists a element '1' such that (3x+5)/1 = (3x+5). adding them up I notice they have different common denominator. My rational expression has a denominator of x^2 and the expression (3x+5) a denominator of 1 Using a theorem called 'common denominator, I multiply (3+5)/1 by x^2/x^2 in order to make the denominator equal so I can traditionally sum my rational expression and the selected one. Which is x^2(sqrt(9x+10)+sqrt6x+5)(swrt9x+10)-sqrt6x+5)+3x+5)x^2/x^2.

maybe that will tell you bacuse im not sure

OpenStudy (jojo4eva):

aye what do you mean by subtract it

OpenStudy (anonymous):

can you just subtract (x-5)
