Since a^2 - b^2 (the difference of two squares) can always be expressed in the form (a+b)(a-b),
x^2 - 16 = x^2 - 4^2 = (x+4)(x-4)

x^2-16 = x^2 -4^2
=(x+4)(x-4)

= x² - 4²
= (x - 4).(x + 4)

x² - 16 = 0
x² - 16 + 16 = 0 + 16
x² = 16
âx² = ± â16
x = ± 4
- - - - - - - - - - - -
x² - 16 = 0
(x - 4)(x + 4) = 0

You really should invest in a photocopier instead of posting a question everytime you want something copied.
