Question Simplify the expression 2−c Evaluate 2−c×1Solution 2−c Show Solution Find the roots c=2 Evaluate 2−c×1To find the roots of the expression,set the expression equal to 0 2−c×1=0Any expression multiplied by 1 remains the same 2−c=0Move the constant to the right-hand side and change its sign −c=0−2Removing 0 doesn't change the value,so remove it from the expression −c=−2Solution c=2 Show Solution
