-y3 + 7y3
It is an algebraic expression.
the answers is d
x^2 - xy + y^2
y3 + 9y + 10y - 5/y + 2 can not be solved, as it is not an equation. If you would like to simplify it, you can reduce it a bit: = y3+ 19y - 5/y + 2
-y3 + 7y3
X2+Y3+15 All you can do is simplify it.
It is an algebraic expression.
No.
(x2 - xy + y2)(x + y)
the answers is d
x^2 - xy + y^2
y3 + 9y + 10y - 5/y + 2 can not be solved, as it is not an equation. If you would like to simplify it, you can reduce it a bit: = y3+ 19y - 5/y + 2
(x4 + y4)/(x + y) = Quotient = x3 - x2y + xy2 - y3 Remainder = - 2y4/(x+y) So, x3 - x2y + xy2 - y3 - 2y4/(x+y)
They don't seem to different at first. But the thing is, Y3 is outdated and old. It may still have the original database of Y8, but Y3 is older. If you notice the layout of the new Y8, it is newer and more user friendly. Plus a really world-known game, Bloons Tower Defense, can't be found on Y3 easily, while Y8 brings the searches instantly. Y8 is better than Y3.
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
6y-y3 = 3
