ALGEBRAIC IDENTITIES
A statement of equality which holds for all values of the variables
IDENTITY 1
(a+b)^2
a(a+b)+b(a+b)
(a+b)(a+b)
a^2+ab+ba+b^2
a^2+2ab+b^2
(a+b)^2= a^2+2ab+b^2
IDENTITY 2
(a-b)^2
a(a-b)-b(a*b)
a^2-ab-ba+b^2
(a-b)(a-b)
a^2-2ab+b^2
(a-b)^2= a^2-2ab+b^2
IDENTITY 3
(a+b)(a-b)
(a+b)(a*b)= a^2-b^2
a^2-ab+ba-b^2
a^2-b^2
a(a-b)+b(a-b)
(x+a)(x+b)
x^2+bx+ax+ab
x^2+ax+bx+ab
x^2+xb+ax+ab
x^2+(a+b)x+ab
x(x+b)+a(x+b)
x^2+qx+r
(x+a)(x+b)
x^2+(a+b)x+ab
