Given equation:
Factor out -1:
Divide both sides by -1:
Rearrange the terms:
Factor the first two terms and the last two terms separately:
Factor out the common term :
<u>Zero Product Property</u>: If a ⋅ b = 0 then either a = 0 or b = 0 (or both).
Using the <u>Zero Product Property</u>, set each factor equal to zero and solve for x (if possible):
Therefore, the solutions to the given equation are: x = 1 or x = -1
