Question
Find the roots
x1=−5,x2=5
Alternative Form
x1≈−2.236068,x2≈2.236068
Evaluate
x2−5
To find the roots of the expression,set the expression equal to 0
x2−5=0
Move the constant to the right-hand side and change its sign
x2=0+5
Removing 0 doesn't change the value,so remove it from the expression
x2=5
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±5
Separate the equation into 2 possible cases
x=5x=−5
Solution
x1=−5,x2=5
Alternative Form
x1≈−2.236068,x2≈2.236068
