Question Simplify the expression 1−2x Evaluate 1×1−2xSolution 1−2x Show Solution Find the roots x=21Alternative Form x=0.5 Evaluate 1×1−2xTo find the roots of the expression,set the expression equal to 0 1×1−2x=0Any expression multiplied by 1 remains the same 1−2x=0Move the constant to the right-hand side and change its sign −2x=0−1Removing 0 doesn't change the value,so remove it from the expression −2x=−1Change the signs on both sides of the equation 2x=1Divide both sides 22x=21Solution x=21Alternative Form x=0.5 Show Solution
