Question Factor the expression 2(2m−1) Evaluate 4m−2Solution 2(2m−1) Show Solution Find the roots m=21Alternative Form m=0.5 Evaluate 4m−2To find the roots of the expression,set the expression equal to 0 4m−2=0Move the constant to the right-hand side and change its sign 4m=0+2Removing 0 doesn't change the value,so remove it from the expression 4m=2Divide both sides 44m=42Divide the numbers m=42Solution m=21Alternative Form m=0.5 Show Solution
