Question
Find the roots
c1=−7,c2=7
Alternative Form
c1≈−2.645751,c2≈2.645751
Evaluate
c2−7
To find the roots of the expression,set the expression equal to 0
c2−7=0
Move the constant to the right-hand side and change its sign
c2=0+7
Removing 0 doesn't change the value,so remove it from the expression
c2=7
Take the root of both sides of the equation and remember to use both positive and negative roots
c=±7
Separate the equation into 2 possible cases
c=7c=−7
Solution
c1=−7,c2=7
Alternative Form
c1≈−2.645751,c2≈2.645751
