Simplify the expression
−3a
Evaluate
a−a−a−a−a
Write the repeated addition as multiplication
a−a×4
Use the commutative property to reorder the terms
a−4a
Collect like terms by calculating the sum or difference of their coefficients
(1−4)a
Solution
−3a
Show Solution
Find the roots
a=0
Evaluate
a−a−a−a−a
To find the roots of the expression,set the expression equal to 0
a−a−a−a−a=0
Subtract the terms
0−a−a−a=0
Removing 0 doesn't change the value,so remove it from the expression
−a−a−a=0
