Question Find the roots Find the roots of the algebra expression x=221Alternative Form x=10.5 Evaluate 2x−21To find the roots of the expression,set the expression equal to 0 2x−21=0Move the constant to the right-hand side and change its sign 2x=0+21Removing 0 doesn't change the value,so remove it from the expression 2x=21Divide both sides 22x=221Solution x=221Alternative Form x=10.5 Show Solution
