Set the factor '(-3 + e)' equal to zero and attempt to solve:

Simplifying
-3 + e = 0

Solving
-3 + e = 0

Move all terms containing e to the left, all other terms to the right.

Add '3' to each side of the equation.
-3 + 3 + e = 0 + 3

Combine like terms: -3 + 3 = 0
0 + e = 0 + 3
e = 0 + 3

Combine like terms: 0 + 3 = 3
e = 3

Simplifying
e = 3
Solution
e = {-3, 3}
