What is the value of (x - 1)(x + 1)(x - 3)(x + 2) when x = 1?

Explanation:
The main idea here is the zero-product property: if any factor in a product is zero, the entire product is zero. When you substitute x = 1, the first factor becomes (1 − 1) = 0. Since you’re multiplying by zero, the whole expression collapses to 0, no matter what the other factors are. So the value is 0.
