Solution
−30−z
Show Solution
Find the roots
z=−30
Evaluate
3−3−3−3−3−3−3−3−3−3−3−3−z
To find the roots of the expression,set the expression equal to 0
3−3−3−3−3−3−3−3−3−3−3−3−z=0
Subtract the terms
0−3−3−3−3−3−3−3−3−3−3−z=0
Removing 0 doesn't change the value,so remove it from the expression
−3−3−3−3−3−3−3−3−3−3−z=0
