difference of 2 square factoring (1-x)(1+x)

Answer 2

even isf the x^2 is negative ?

yes, because 1 and x^2 are both perfect squares and they are separated by a - sign. Multiply the factored form that I gave you and you'll get what you started with.

Answer 4

Difference of squares (a^2-b^2) = (a+b)(a-b)

Answer 5

\[(a+b)(a-b) = a(a-b) + b(a-b) = a^2 -ab +ba -b^2 = a^2-b^2\]

Answer 6

x^2-1 is (x+1)(x-1)

Answer 7

Answer 11

ab and ba cancel each other. that is why
(a+b)(a-b) = a^2-b^2
