If x = 0 and blah ≠ 0, what is the value of the expression?

When you substitute x = 0, any part of the expression that involves x drops out. If the remaining pieces form a ratio where the numerator and denominator become the same nonzero quantity, the value is 1. A common pattern is something like a squared difference over the square of the nonzero term: (blah − x)² / blah². With x = 0 this becomes blah² / blah² = 1, as long as blah ≠ 0 to avoid division by zero. This nonzero condition is essential. If the expression were arranged differently, other values could occur, but in this setup the result is 1.
