Question Simplify the expression −t Evaluate t−t−tCollect like terms by calculating the sum or difference of their coefficients (1−1−1)tSolution −t Show Solution Find the roots t=0 Evaluate t−t−tTo find the roots of the expression,set the expression equal to 0 t−t−t=0Subtract the terms 0−t=0Removing 0 doesn't change the value,so remove it from the expression −t=0Solution t=0 Show Solution
