Question
Find the roots
c1=−15,c2=15
Alternative Form
c1≈−3.872983,c2≈3.872983
Evaluate
c2−15
To find the roots of the expression,set the expression equal to 0
c2−15=0
Move the constant to the right-hand side and change its sign
c2=0+15
Removing 0 doesn't change the value,so remove it from the expression
c2=15
Take the root of both sides of the equation and remember to use both positive and negative roots
c=±15
Separate the equation into 2 possible cases
c=15c=−15
Solution
c1=−15,c2=15
Alternative Form
c1≈−3.872983,c2≈3.872983
