factorize : \[\large{x^2+(a+b+c)x+ab+bc}\]

mathslover (mathslover):

I did like this : \[\large{x^2+ax+bx+cx+ab+ac}\] \[\large{x^2+bx+cx+ax+ab+ac}\] \[\large{x(x+b+c)+a(x+b+c)}\] \[\large{(x+a)(x+b+c)}\]

OpenStudy (anonymous):

Good..

OpenStudy (vishweshshrimali5):

Its absolutely correct.........

mathslover (mathslover):

but the book shows answer as : \[\large{(x+b)(x+a+c)}\] which is wrong

mathslover (mathslover):

so book is wrong?

OpenStudy (vishweshshrimali5):

well its easy to check just simplify the book's answer

OpenStudy (anonymous):

How can @mathslover be wrong.. Misprint will be in book..

OpenStudy (vishweshshrimali5):

Yes the book has factorised. \[x^2 + (a+b+c) x + ab + bc\]

mathslover (mathslover):

yes it is right also : \[\large{(x+b)(x+a+c)}\] \[\large{x^2+ax+cx+bx+ab+cb}\] \[\large{x^2+x(a+b+c)+ab+bc}\]

mathslover (mathslover):

\[\large{(x+a)(x+b+c)}\] \[\large{x^2+bx+cx+ax+ab+ac}\] even i am wrong

mathslover (mathslover):

oh sorry i wrote the question wrong it was bc

OpenStudy (anonymous):

No how you got cb in last ??

OpenStudy (vishweshshrimali5):

You are not wrong........... This is what the question is ...... ?

OpenStudy (anonymous):

@mathslover you have done a mistake in reading question..

OpenStudy (vishweshshrimali5):

:D That's what I used to do.........

OpenStudy (anonymous):

There is bc in the last and not ac as you had written earlier..

mathslover (mathslover):

sorry for the mistake : so here i go with the correct one: \[\large{x^2+(a+b+c)x+ab+bc}\] \[\large{x^2+ax+bx+cx+ab+bc}\] \[\large{x^2+ax+cx+ab+bc+bx}\] \[\large{x(x+a+c)+b(x+a+c)}\] \[\large{(x+b)(x+a+c)}\]

mathslover (mathslover):

so it is right now?

OpenStudy (vishweshshrimali5):

Very nice

OpenStudy (anonymous):

Well Done..

mathslover (mathslover):
