The GCF is y4
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
x2 + y4 + x4 +y2 = x6 + y6unless you know what x and y are.* * * * *x2 + y4 + x4 + y2 ??I don't believe that this expression can be factorised or otherwise simplified.It certainly does not equal x6 + y6,for all x and all y:for example, if x = y = 1, thenx2 + y4 + x4 + y2 = 4, whilstx6 + y6 = 2;thus, they are two manifestly unequal quantities.
18xy is the GCF of 72x2y and 18xy
The product of y times 4 is equal to y multiplied by 4. Similarly, the product of y times 6 is equal to y multiplied by 6.
3-y6 = -3
The GCF is y6.
x=y4 /2
4x-y4 what = 0
The simplest equation would be y4 = 0
(x2 + y2)(x + y)(x - y) = x4 - y4.
The coefficient is 1.6
