x3+xy-x2y2=x(x2+y-xy2)
IMPOSSIBLE
No.
It is x = -5
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
x3+xy-x2y2=x(x2+y-xy2)
X3 + 8= (x+2)(x2-2x+4)
-24
IMPOSSIBLE
No.
X(X2 - X)
y2=x3+3x2
No, it is not.
It is x = -5
(xn+2-1)/(x2-1)
If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator
