Question Factor the expression (w−1)(w2+w+1) Evaluate w3−1Rewrite the expression in exponential form w3−13Use a3−b3=(a−b)(a2+ab+b2) to factor the expression (w−1)(w2+w×1+12)Any expression multiplied by 1 remains the same (w−1)(w2+w+12)Solution (w−1)(w2+w+1) Show Solution Find the roots w=1 Evaluate w3−1To find the roots of the expression,set the expression equal to 0 w3−1=0Move the constant to the right-hand side and change its sign w3=0+1Removing 0 doesn't change the value,so remove it from the expression w3=1Take the 3-th root on both sides of the equation 3w3=31Calculate w=31Solution w=1 Show Solution
