Question Simplify the expression 2x2−4x Evaluate (2x×1)(x−2)Remove the parentheses 2x×1×(x−2)Any expression multiplied by 1 remains the same 2x(x−2)Apply the distributive property 2x×x−2x×2Multiply the terms 2x2−2x×2Solution 2x2−4x Show Solution Find the roots x1=0,x2=2 Evaluate (2x×1)(x−2)To find the roots of the expression,set the expression equal to 0 (2x×1)(x−2)=0Multiply the terms 2x(x−2)=0Elimination the left coefficient x(x−2)=0Separate the equation into 2 possible cases x=0x−2=0Solve the equation More Steps Evaluate x−2=0Move the constant to the right-hand side and change its sign x=0+2Removing 0 doesn't change the value,so remove it from the expression x=2 x=0x=2Solution x1=0,x2=2 Show Solution
