Question
Find the roots
x1=−82,x2=82
Alternative Form
x1≈−9.055385,x2≈9.055385
Evaluate
82−x2
To find the roots of the expression,set the expression equal to 0
82−x2=0
Move the constant to the right-hand side and change its sign
−x2=0−82
Removing 0 doesn't change the value,so remove it from the expression
−x2=−82
Change the signs on both sides of the equation
x2=82
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±82
Separate the equation into 2 possible cases
x=82x=−82
Solution
x1=−82,x2=82
Alternative Form
x1≈−9.055385,x2≈9.055385
