Question Simplify the expression d2−d Evaluate d2−d×1Solution d2−d Show Solution Factor the expression d(d−1) Evaluate d2−d×1Any expression multiplied by 1 remains the same d2−dRewrite the expression d×d−dSolution d(d−1) Show Solution Find the roots d1=0,d2=1 Evaluate d2−d×1To find the roots of the expression,set the expression equal to 0 d2−d×1=0Any expression multiplied by 1 remains the same d2−d=0Factor the expression More Steps Evaluate d2−dRewrite the expression d×d−dFactor out d from the expression d(d−1) d(d−1)=0When the product of factors equals 0,at least one factor is 0 d=0d−1=0Solve the equation for d More Steps Evaluate d−1=0Move the constant to the right-hand side and change its sign d=0+1Removing 0 doesn't change the value,so remove it from the expression d=1 d=0d=1Solution d1=0,d2=1 Show Solution
