x^3+y^3 Cube root of the first, x plus cube root of the last, y times What it takes to make the first number, x^2 Opposite sign, - Product of the two cube roots, -xy Then what it takes to make the last. (x+y)(X^2-xy+y^2)
x times y is "xy"
It is: x times y or as xy
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
It equals XY.
So far you know that: x=-8 xy=1 so xy means x times y. If you split xy. y=1/x or y=1/-8 1/-8= -0.125 You can find out that this is correct with the formula xy=1 because -0.125 x -8 is 1.
If that's y times 4, the answer is 4y
x times y or, symbolically, either x*y or simply xy (where context allows, also X x Y)
The GCF is xy
xy = x ÷x y = 1
It is XY^2 or X*Y*Y
x+xy=8 xy=-x+8 y=-1+8/x
(x-y) + (xy - 1) = (x - 1)(y + 1)
