 Question 243271: I'm stuck on the Factoring section of the current unit I'm in for College Algebra. I don't understand it & can't even begin to figure this out. I have a few problems that I need help with. Thank you! x^10y^3 – 4x^9y^2 – 21x^8y x^3 – 2x^2 + 7x – 14 x^2 + 9x + 8 8x^2 – 200y^2 7x^2 + 58x + 16 7x^2 + 49x + 42 The assignment says to "Factor Completely"... I don't understand that.
