Question Simplify the expression 1−10x+40x2−80x3+80x4−32x5 Evaluate (1−2x)5Solution 1−10x+40x2−80x3+80x4−32x5 Show Solution Find the roots x=21Alternative Form x=0.5 Evaluate (1−2x)5To find the roots of the expression,set the expression equal to 0 (1−2x)5=0The only way a power can be 0 is when the base equals 0 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
