Question Factor the expression (1−w)(1+w) Evaluate 1−w2Rewrite the expression in exponential form 12−w2Solution (1−w)(1+w) Show Solution Find the roots w1=−1,w2=1 Evaluate 1−w2To find the roots of the expression,set the expression equal to 0 1−w2=0Move the constant to the right-hand side and change its sign −w2=0−1Removing 0 doesn't change the value,so remove it from the expression −w2=−1Change the signs on both sides of the equation w2=1Take the root of both sides of the equation and remember to use both positive and negative roots w=±1Simplify the expression w=±1Separate the equation into 2 possible cases w=1w=−1Solution w1=−1,w2=1 Show Solution
