Simplify the expression
−3d
Evaluate
d−d−d−d−d
Write the repeated addition as multiplication
d−d×4
Use the commutative property to reorder the terms
d−4d
Collect like terms by calculating the sum or difference of their coefficients
(1−4)d
Solution
−3d

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