DISA FORMULA KRYESORE ALGJEBRIKE

(a+b)2=a2+2ab+b2(a+b)^{2}=a^{2}+2ab+b^{2}
(a−b)2=a2−2ab+b2(a-b)^{2}=a^{2}-2ab+b^{2}
(a+b)3=a3+3a2b+3ab2+b3(a+b)^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3}
a2−b2=(a−b)(a+b)a^{2}-b^{2} = (a-b)(a+b)
a3−b3=(a−b)(a2+ab+b2)a^{3}-b^{3} = (a-b)(a^{2}+ab+b^{2})
an−bn=(a−b)(an−1+an−2b+an−3b2+...+bn−1)a^{n}-b^{n} = (a-b)(a^{n-1}+a^{n-2}b+a^{n-3}b^{2}+...+b^{n-1})
