Question Simplify the expression 2013−a Evaluate ∣2013∣−1×aWhen the expression in absolute value bars is not negative, remove the bars 2013−1×aSolution 2013−a Show Solution Find the roots a=2013 Evaluate ∣2013∣−1×aTo find the roots of the expression,set the expression equal to 0 ∣2013∣−1×a=0When the expression in absolute value bars is not negative, remove the bars 2013−1×a=0Any expression multiplied by 1 remains the same 2013−a=0Move the constant to the right-hand side and change its sign −a=0−2013Removing 0 doesn't change the value,so remove it from the expression −a=−2013Solution a=2013 Show Solution
