Question
Find the roots
f1=−347,f2=347
Alternative Form
f1≈−20.566964,f2≈20.566964
Evaluate
f2−423
To find the roots of the expression,set the expression equal to 0
f2−423=0
Move the constant to the right-hand side and change its sign
f2=0+423
Removing 0 doesn't change the value,so remove it from the expression
f2=423
Take the root of both sides of the equation and remember to use both positive and negative roots
f=±423
Simplify the expression
