Answer 2

Solution:-

$\qquad\quad {:}\longmapsto\sf (x+1)(x^2-x+1)$

• Let's use distributive formula :

${\boxed{\sf (a+b)(c+d)=a (c+d)+b (c+d)}}$

• Substitute the values :

$\qquad\quad {:}\longmapsto\sf x (x^2-x+1)+1 (x^2-x+1)$

• Simplify :

$\qquad\quad {:}\longmapsto\sf x^3-x^2+x+x^2-x+1$

• Now together like variables :

$\qquad\quad {:}\longmapsto\sf x^3-x^2+x^2+x-x+1$

• Simplify :

$\qquad\quad {:}\longmapsto\sf x^3+0+0+1$

$\qquad\quad {:}\longmapsto{\underline {\boxed{\bf x^3+1}}}$
