X ^3 + 6x^2 + 12x+8 : (x+2)

X^2+4x+4 and there is no remainder

you cant solve it, since we need and = sign and other numbers on that side,

but you can simplify it to (x^2+4x+4)

Step-by-step explanation:

x^3+6x^2+12x+8 / x+2

= (x+2) (x+2) (x+2) / x+2

=x^2+4x+4, since you cancel out one of the numerators (x+2) with the denominator
