Question Factor the expression (x−1)(x2+x+1) Evaluate x3−1Calculate x3+x2+x−x2−x−1Rewrite the expression x×x2+x×x+x−x2−x−1Factor out x from the expression x(x2+x+1)−x2−x−1Factor out −1 from the expression x(x2+x+1)−(x2+x+1)Solution (x−1)(x2+x+1) Show Solution Find the roots x=1 Evaluate (x3−1)To find the roots of the expression,set the expression equal to 0 x3−1=0Move the constant to the right-hand side and change its sign x3=0+1Removing 0 doesn't change the value,so remove it from the expression x3=1Take the 3-th root on both sides of the equation 3x3=31Calculate x=31Solution x=1 Show Solution
