Best ResponseYou've already chosen the best response.2take out common factor let sin x=y so y^2 +y what's the common factor ?

Best ResponseYou've already chosen the best response.0This is \(\large sin^2(x) + sin(x) = 0\) right? or \(\large sin(2x) + sin(x) = 0\) ?

Best ResponseYou've already chosen the best response.0Then perfect go ahead with the process @Nnesha was showing :) Look at it as sin(x) = y so sin^2(x) = y^2 \[\large y^2 + y = 0\] What can you factor out?

Best ResponseYou've already chosen the best response.1so you have no idea how to factor y^2+y=0? what is common btw y^2 and y?

Best ResponseYou've already chosen the best response.1let's us go to the basics how can you do this a(b+c)=? using distributive law?

Best ResponseYou've already chosen the best response.1ok back let's pick it up where i left it know of distributive law?

Best ResponseYou've already chosen the best response.1realize that is the basic math? from lower grades

xapproachesinfinity

Best ResponseYou've already chosen the best response.1so distributive law tells us that a(b+c)=ab+ac the left hand side is the same are the right hand side any doubt that it true?

xapproachesinfinity

Best ResponseYou've already chosen the best response.1i said do you agree that a(b+c)=ab+ac or against this arithmetic law? the problem here is we need to establish some sense first before we tackle that problem of your that deals with trig

Best ResponseYou've already chosen the best response.1so you have no problem to tell what this is gonna be bd+be=? using the same law?

xapproachesinfinity

Best ResponseYou've already chosen the best response.1oh well! so it is gonna be bd+be=b(d+e) yes?

Best ResponseYou've already chosen the best response.0u factored y^2 and y

xapproachesinfinity

Best ResponseYou've already chosen the best response.1no just stay on what i did that would come later! what i'm trying to do here to show you how we can accomplish the factorization for y^2+y

Best ResponseYou've already chosen the best response.1i want you to fully understand this! so you will have further problem with such exercice!

xapproachesinfinity

Best ResponseYou've already chosen the best response.1so here really what i did is using the that very distributive law of arithmetic to get from bd+be to b(d+e)

xapproachesinfinity

Best ResponseYou've already chosen the best response.1ok let me test one more time xy+2x=?

xapproachesinfinity

Best ResponseYou've already chosen the best response.1again distributive law!

Best ResponseYou've already chosen the best response.1this is all for the sake of you being better at this, if that's the case then it is really fine with me we can gave you the answer, but what is the point of doing it any way

Best ResponseYou've already chosen the best response.1i can tell oh this and that an such then this is the answer next time you have test you stuck! who is there to give you the answer no one no you are not dumb. you are resisting this is that is all

Best ResponseYou've already chosen the best response.2i asked a question how many chocolates they both people have n common ?

Nnesha

Best ResponseYou've already chosen the best response.2how ?? remember exponent represent number of chocolates dw:1433893136376:dw

anonymous

Best ResponseYou've already chosen the best response.0once has 2 and the other has 1

Nnesha

Best ResponseYou've already chosen the best response.2so common number of chocolate would be one right or you can apply exponent rule \[\huge\rm x^m \times x^n = x^{m +n}\] so that's how y times y = y^2\[\huge\rm (y \times y \color{red}{+} y)\] so what's common in thes both terms ?
