Answer:

(x - 43)(x + 43)

Step-by-step explanation:

x² - 43² ← is a difference of squares and factorises in general as

a² - b² = (a - b)(a + b), then

x² - 43²

= (x - 43)(x + 43)

Answer:

(x - 43)(x + 43).

Step-by-step explanation:

This is the difference of 2 squares:

a^2 - b^2 = (a - b)(a + b) so here we have:

x^2 - 43^2 = (x - 43)(x + 43).
