Question Factor the expression (p−1)(p2+p+1) Evaluate p3−1Calculate p3+p2+p−p2−p−1Rewrite the expression p×p2+p×p+p−p2−p−1Factor out p from the expression p(p2+p+1)−p2−p−1Factor out −1 from the expression p(p2+p+1)−(p2+p+1)Solution (p−1)(p2+p+1) Show Solution Find the roots p=1 Evaluate (p3−1)To find the roots of the expression,set the expression equal to 0 p3−1=0Move the constant to the right-hand side and change its sign p3=0+1Removing 0 doesn't change the value,so remove it from the expression p3=1Take the 3-th root on both sides of the equation 3p3=31Calculate p=31Solution p=1 Show Solution
