Question Factor the expression (1−x)(1+x+x2) Evaluate 1−x3Rewrite the expression in exponential form 13−x3Use a3−b3=(a−b)(a2+ab+b2) to factor the expression (1−x)(12+1×x+x2)1 raised to any power equals to 1 (1−x)(1+1×x+x2)Solution (1−x)(1+x+x2) Show Solution Find the roots x=1 Evaluate 1−x3To find the roots of the expression,set the expression equal to 0 1−x3=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=−1Change the signs on both sides of the equation x3=1Take the 3-th root on both sides of the equation 3x3=31Calculate x=31Solution x=1 Show Solution
