Question 65019: How do I go about simplyfing this?
y^3(10x^2 + 3y-1)(5x^3 - 3xy - y)
Answer by stanbon(75887) About Me  (Show Source):
You can put this solution on YOUR website!
y^3(10x^2 + 3y-1)(5x^3 - 3xy - y)
That's a long complicated problem.
Every term of 5x^3-3xy-y must be
multiplied by every term of 10x^2+3y-1
That gives you 9 different multiplications.
Then each of those 9 terms must be multiplied
by y^3.
Hope that helps.
