Question
x2−68
Find the roots
x1=−217,x2=217
Alternative Form
x1≈−8.246211,x2≈8.246211
Evaluate
x2−68
To find the roots of the expression,set the expression equal to 0
x2−68=0
Move the constant to the right-hand side and change its sign
x2=0+68
Removing 0 doesn't change the value,so remove it from the expression
x2=68
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±68
Simplify the expression
