Question
Find the roots
x1=−10,x2=10
Alternative Form
x1≈−3.162278,x2≈3.162278
Evaluate
x2−10
To find the roots of the expression,set the expression equal to 0
x2−10=0
Move the constant to the right-hand side and change its sign
x2=0+10
Removing 0 doesn't change the value,so remove it from the expression
x2=10
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±10
Separate the equation into 2 possible cases
x=10x=−10
Solution
x1=−10,x2=10
Alternative Form
x1≈−3.162278,x2≈3.162278
