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