Question Factor the expression (m−1)(m+1) Evaluate m2−1Rewrite the expression in exponential form m2−12Solution (m−1)(m+1) Show Solution Find the roots m1=−1,m2=1 Evaluate m2−1To find the roots of the expression,set the expression equal to 0 m2−1=0Move the constant to the right-hand side and change its sign m2=0+1Removing 0 doesn't change the value,so remove it from the expression m2=1Take the root of both sides of the equation and remember to use both positive and negative roots m=±1Simplify the expression m=±1Separate the equation into 2 possible cases m=1m=−1Solution m1=−1,m2=1 Show Solution
