Question Simplify the expression z2−z Evaluate (z−1)(z×1)Remove the parentheses (z−1)z×1Rewrite the expression (z−1)zMultiply the terms z(z−1)Apply the distributive property z×z−z×1Multiply the terms z2−z×1Solution z2−z Show Solution Find the roots z1=0,z2=1 Evaluate (z−1)(z×1)To find the roots of the expression,set the expression equal to 0 (z−1)(z×1)=0Any expression multiplied by 1 remains the same (z−1)z=0Multiply the terms z(z−1)=0Separate the equation into 2 possible cases z=0z−1=0Solve the equation More Steps Evaluate z−1=0Move the constant to the right-hand side and change its sign z=0+1Removing 0 doesn't change the value,so remove it from the expression z=1 z=0z=1Solution z1=0,z2=1 Show Solution
