Question
Find the roots
x1=−2203,x2=2203
Alternative Form
x1≈−28.495614,x2≈28.495614
Evaluate
x2−812
To find the roots of the expression,set the expression equal to 0
x2−812=0
Move the constant to the right-hand side and change its sign
x2=0+812
Removing 0 doesn't change the value,so remove it from the expression
x2=812
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±812
Simplify the expression
