Question Simplify the expression 2r2−2r Evaluate (2r×1)(r−1)Remove the parentheses 2r×1×(r−1)Any expression multiplied by 1 remains the same 2r(r−1)Apply the distributive property 2r×r−2r×1Multiply the terms 2r2−2r×1Solution 2r2−2r Show Solution Find the roots r1=0,r2=1 Evaluate (2r×1)(r−1)To find the roots of the expression,set the expression equal to 0 (2r×1)(r−1)=0Multiply the terms 2r(r−1)=0Elimination the left coefficient r(r−1)=0Separate the equation into 2 possible cases r=0r−1=0Solve the equation More Steps Evaluate r−1=0Move the constant to the right-hand side and change its sign r=0+1Removing 0 doesn't change the value,so remove it from the expression r=1 r=0r=1Solution r1=0,r2=1 Show Solution
