Find the roots
p1=−26−22i,p2=26+22i
Alternative Form
p1≈−1.224745−0.707107i,p2≈1.224745+0.707107i
Evaluate
p6+8
To find the roots of the expression,set the expression equal to 0
p6+8=0
Move the constant to the right-hand side and change its sign
p6=0−8
Removing 0 doesn't change the value,so remove it from the expression
p6=−8
Take the root of both sides of the equation and remember to use both positive and negative roots
p=±6−8
