Question
Find the roots
x1=−π,x2=π
Alternative Form
x1≈−1.772454,x2≈1.772454
Evaluate
π−x2
To find the roots of the expression,set the expression equal to 0
π−x2=0
Move the constant to the right-hand side and change its sign
−x2=0−π
Removing 0 doesn't change the value,so remove it from the expression
−x2=−π
Change the signs on both sides of the equation
x2=π
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±π
Separate the equation into 2 possible cases
x=πx=−π
Solution
x1=−π,x2=π
Alternative Form
x1≈−1.772454,x2≈1.772454
