-y3 + 7y3
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
X2+Y3+15 All you can do is simplify it.
It is an algebraic expression.
Lets start by putting the known number on the other side. Y3 -7500y=125000. There is your start. Take it from here.
No.
No, because it is not an equation (or inequality), but simply two expressions separated by a space.
(x2 - xy + y2)(x + y)
That factors to y(y2 + 7y - 5)
the answers is d
16y3 / 20y4 = 16/20 * y3/y4 = 4/5 * y3-4 = 4/5 * y-1 or 4/5y
x^2 - xy + y^2
