Question Factor the expression (a−2)(a2+2a+4) Evaluate a3−8Rewrite the expression in exponential form a3−23Use a3−b3=(a−b)(a2+ab+b2) to factor the expression (a−2)(a2+a×2+22)Use the commutative property to reorder the terms (a−2)(a2+2a+22)Solution (a−2)(a2+2a+4) Show Solution Find the roots a=2 Evaluate a3−8To find the roots of the expression,set the expression equal to 0 a3−8=0Move the constant to the right-hand side and change its sign a3=0+8Removing 0 doesn't change the value,so remove it from the expression a3=8Take the 3-th root on both sides of the equation 3a3=38Calculate a=38Solution More Steps Evaluate 38Write the number in exponential form with the base of 2 323Reduce the index of the radical and exponent with 3 2 a=2 Show Solution
