How do you solve 3x^2+9xy+6x^2=(3x+6y)*w for w?

OpenStudy (anonymous):

Divide both sides by 3x+6y

OpenStudy (mathstudent55):

Since w is only on the right side multiplied by a factor, divide both sides by that factor

OpenStudy (anonymous):

done

OpenStudy (anonymous):

what do I do next?

OpenStudy (mathstudent55):

Now try to factor the numerator on the left. First divide it by three. The factor you divided by 3x + 6y can also be factored. A 3 comes out.

OpenStudy (anonymous):

how?

OpenStudy (anonymous):

Is it 3(x^2+3xy+2y^2)?

OpenStudy (anonymous):

over 6y?
