The expression x² – 100 is a difference of squares, which can be factored using the formula a² – b² = (a – b)(a + b). In this case, we can identify a as x and b as 10 since 100 is equal to 10².
Using the formula, we can factor the expression:
x² – 100 = (x – 10)(x + 10)
Thus, the factors of x² – 100 are (x – 10) and (x + 10). These factors show that if you multiply (x – 10) and (x + 10), you will return to the original expression x² – 100.
