Question
Find the roots
d1=−510,d2=510
Alternative Form
d1≈−15.811388,d2≈15.811388
Evaluate
d2−250
To find the roots of the expression,set the expression equal to 0
d2−250=0
Move the constant to the right-hand side and change its sign
d2=0+250
Removing 0 doesn't change the value,so remove it from the expression
d2=250
Take the root of both sides of the equation and remember to use both positive and negative roots
d=±250
Simplify the expression
