Sagot :
To factor "Difference of two squares" :
Example:
x²-4
∞ Get the square root of the first term and last term,then write it as two factors with opposite signs (one negative and one positive)
√x² = x and √4 = 2
(x-2)(x+2)
P.S. Hope that helps ^_^

Difference of two squares= its factors is sum and and difference of 2 same terms.
Ex.
x²-9
(x+3) (x-3)
the additionsame is always in the first
