Question
Factor the expression
(x−12)(x+12)
Evaluate
x2−144
Rewrite the expression in exponential form
x2−122
Solution
(x−12)(x+12)
Show Solution
Find the roots
x1=−12,x2=12
Evaluate
x2−144
To find the roots of the expression,set the expression equal to 0
x2−144=0
Move the constant to the right-hand side and change its sign
x2=0+144
Removing 0 doesn't change the value,so remove it from the expression
x2=144
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±144
Simplify the expression
