I think I did this totally wrong. I need to go reread the lessons again.
first use foil to expand y=(x-5)(5x+4)-5x^2
y=(x-5)(5x+4)-5x^2 y = (5x^2+4x-25x-20) - 5x^2, with me so far?
okay I think I gotcha
then we combine like terms and simplify y = (5x^2+4x-25x-20) - 5x^2 = -21x - 20
"linear term" is whatever the x term is, so in this case out linear term is -21x
and our constant term is -20 (the term with no variable attached to it)
huh that was easier than I thought. I missed the part about using foil. Okay so that's the linear term. I was correct about the constant term? It's -20
okay I didn't see you're reply yet. I got it right. Thank you for showing me that :) It's much appreciated
no problem. it would also be good to learn the foil method which will be helpful in the future http://www.freemathhelp.com/using-foil.html
