Is this Right?Date: Mon, 09 Jan 1995 17:12:09 AST From: Richard Seguin Subject: math How do you do a question like this? 2y(3y+1)-3(3y+1)+y(y+2) I found to go like this Add your commons 6Y^2 -8Y+4Y Is this Right? Date: Mon, 9 Jan 1995 16:37:58 -0500 (EST) From: Dr. Ken Subject: Re: math Hello there! It's almost right. If you multiply these terms out, you'll get 6y^2 + 2y - 9y - 3 + y^2 + 2y. And then you add common terms to get (6+1)y^2 + (2-9+2)y -3 , which equals 7y^2 - 5y - 3. If you didn't follow any of these steps, please write back and we'll try to help you. -Ken "Dr." Math |
