Question
Find the roots
d1=−402,d2=402
Alternative Form
d1≈−20.049938,d2≈20.049938
Evaluate
d2−402
To find the roots of the expression,set the expression equal to 0
d2−402=0
Move the constant to the right-hand side and change its sign
d2=0+402
Removing 0 doesn't change the value,so remove it from the expression
d2=402
Take the root of both sides of the equation and remember to use both positive and negative roots
d=±402
Separate the equation into 2 possible cases
d=402d=−402
Solution
d1=−402,d2=402
Alternative Form
d1≈−20.049938,d2≈20.049938
