Question
Find the roots
f1=−42,f2=42
Alternative Form
f1≈−6.480741,f2≈6.480741
Evaluate
f2−42
To find the roots of the expression,set the expression equal to 0
f2−42=0
Move the constant to the right-hand side and change its sign
f2=0+42
Removing 0 doesn't change the value,so remove it from the expression
f2=42
Take the root of both sides of the equation and remember to use both positive and negative roots
f=±42
Separate the equation into 2 possible cases
f=42f=−42
Solution
f1=−42,f2=42
Alternative Form
f1≈−6.480741,f2≈6.480741
