Question
Find the roots
d1=−55,d2=55
Alternative Form
d1≈−11.18034,d2≈11.18034
Evaluate
d2−125
To find the roots of the expression,set the expression equal to 0
d2−125=0
Move the constant to the right-hand side and change its sign
d2=0+125
Removing 0 doesn't change the value,so remove it from the expression
d2=125
Take the root of both sides of the equation and remember to use both positive and negative roots
d=±125
Simplify the expression
