Question Factor the expression (p−1)(p+1) Evaluate p2−1Rewrite the expression in exponential form p2−12Solution (p−1)(p+1) Show Solution Find the roots p1=−1,p2=1 Evaluate p2−1To find the roots of the expression,set the expression equal to 0 p2−1=0Move the constant to the right-hand side and change its sign p2=0+1Removing 0 doesn't change the value,so remove it from the expression p2=1Take the root of both sides of the equation and remember to use both positive and negative roots p=±1Simplify the expression p=±1Separate the equation into 2 possible cases p=1p=−1Solution p1=−1,p2=1 Show Solution
