Question

x^3-x^2+x-1=x^2+1

Answer 1

@tom982 Wanna help explain this one real quick?

Answer 2

x^3-2x^2+x-2=0

Answer 3

Could you cross out the -x^2 with the x^2?

Answer 4

And get like x^3+x-2=0?

Answer 5

Well, no because they're on opposites of the equation.

Answer 6

x^3 +x^2 +x +1 = 0
Separate : ( x^3 +x^2 ) + ( x +1 ) = 0
Commutative Law : ( x^3 +x ) + ( x^2 +1 ) = 0
Distributive Law : x*( x^2 +1 ) + +*( x^2 +1 ) = 0
Factor : ( x +1 )*( x^2 +1 ) = 0
