Question
Find the roots
d1=−155,d2=155
Alternative Form
d1≈−12.4499,d2≈12.4499
Evaluate
d2−155
To find the roots of the expression,set the expression equal to 0
d2−155=0
Move the constant to the right-hand side and change its sign
d2=0+155
Removing 0 doesn't change the value,so remove it from the expression
d2=155
Take the root of both sides of the equation and remember to use both positive and negative roots
d=±155
Separate the equation into 2 possible cases
d=155d=−155
Solution
d1=−155,d2=155
Alternative Form
d1≈−12.4499,d2≈12.4499
