Question Factor the expression (h−1)(h4+h3+h2+h+1) Evaluate h5−1Calculate h5+h4+h3+h2+h−h4−h3−h2−h−1Rewrite the expression h×h4+h×h3+h×h2+h×h+h−h4−h3−h2−h−1Factor out h from the expression h(h4+h3+h2+h+1)−h4−h3−h2−h−1Factor out −1 from the expression h(h4+h3+h2+h+1)−(h4+h3+h2+h+1)Solution (h−1)(h4+h3+h2+h+1) Show Solution Find the roots h=1 Evaluate h5−1To find the roots of the expression,set the expression equal to 0 h5−1=0Move the constant to the right-hand side and change its sign h5=0+1Removing 0 doesn't change the value,so remove it from the expression h5=1Take the 5-th root on both sides of the equation 5h5=51Calculate h=51Solution h=1 Show Solution
