Question

what pattern is seen in the factors of difference of two squares?​

Answer 1

$\huge{\bold{\blue{\mathcal{Answer:}}}}$

By designing mass spectrometers that can determine m/z values accurately to four decimal places, it is possible to distinguish different formulas having the same nominal mass. The table on the right illustrates this important feature, and a double-focusing high-resolution mass spectrometer easily distinguishes ions having these compositions.

Answer 2

The big three patterns to know are, the square of a sum (a + b) squared = a squared + 2ab + b squared. The square of a difference (a- b) squared is a squared- 2ab + b squared.
