Question

(x+1)(x²-x+1)

(x-3)(x²+3x+9)

(x-2)(x²+2x+4)

Answer 1

\(\left(x+1\right)\left(x^2-x+1\right)=x^3+1\\ \left(x-3\right)\left(x^2+3x+9\right)=x^3-27\\ \left(x-2\right)\left(x^2+2x+4\right)=x^3-8\)

Answer 2

\(\left(x+1\right)\left(x^2-x+1\right)=x^3+1\)

\(\left(x-3\right)\left(x^2+3x+9\right)=x^3-27\)

\(\left(x-2\right)\left(x^2+2x+4\right)=x^3-8\)
