Question
Find the roots
f1=−19,f2=19
Alternative Form
f1≈−4.358899,f2≈4.358899
Evaluate
f2−19
To find the roots of the expression,set the expression equal to 0
f2−19=0
Move the constant to the right-hand side and change its sign
f2=0+19
Removing 0 doesn't change the value,so remove it from the expression
f2=19
Take the root of both sides of the equation and remember to use both positive and negative roots
f=±19
Separate the equation into 2 possible cases
f=19f=−19
Solution
f1=−19,f2=19
Alternative Form
f1≈−4.358899,f2≈4.358899
