Question

(a+b) (a-b) expontion of
​

Answer 1

Answer:

a^2-b^2 is the expansion

Step-by-step explanation:

sol: (a+b)(a-b)

=a*a-a*b+a*a-b*b

=a^2-b^2+a*b-a*b

=a^2-b^2

hope you got the point

Answer 2

Answer:

(a + b)2 = a2 + 2 ab + b2 (8). (a - b)2 ... ( a - b)3 = a3 - 3a2b + 3 ab2 - b3 (11) ... a3 - b3 = (a - b)3 + 3 a b (a - b) (13) ... en: Factors expansion; es: Factores de expansión; de: Faktoren Expansion
