Question Factor the expression (r−2)(r2+2r+4) Evaluate r3−8Rewrite the expression in exponential form r3−23Use a3−b3=(a−b)(a2+ab+b2) to factor the expression (r−2)(r2+r×2+22)Use the commutative property to reorder the terms (r−2)(r2+2r+22)Solution (r−2)(r2+2r+4) Show Solution Find the roots r=2 Evaluate r3−8To find the roots of the expression,set the expression equal to 0 r3−8=0Move the constant to the right-hand side and change its sign r3=0+8Removing 0 doesn't change the value,so remove it from the expression r3=8Take the 3-th root on both sides of the equation 3r3=38Calculate r=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 r=2 Show Solution
