Slove
X^3- 3x^2+ 5x = 1
Y^3 -3y^2 +5y = 5

[TURNKEYiNK]

Nice explanation. Thanks.
What do you do if, for example, the last value is a Prime Number: 47 instead of 45, as in the last example.

[MrHaunted]

Proof that math can be easy if you get the right teacher

9x^3-12x^2-3x+4
3x^2(3x-4)-1(3x-4)
(3x^2-1)(3x-4)

[ChavoMysterio]

2x^3+5x^2-18x-45
x^2(2x+5)-9(2x+5)
(x^2-9)(2x+5)
(x+3)(x-3)(2x+5)

[lavaniadelrey]

Thanks! Still difficult but I’ll manage
