Question

$1. (a+b)^2 = a^2 + b^2 + 2ab\\2. (a-b)^2 = a^2 + b^2 - 2ab\\3. a^2 - b^2 = (a-b)(a+b)\\4. (x+a)(x+b) = x^2 + (a+b)x +ab\\5. (a+b+c)^2 = a^2 + b^2 + c^2 +2ab +2bc+2ca\\6. (a+b)^3 = a^3 + b^3 +3ab(a+b)\\7.(a-b)^3 = a^3 - b^3 -3ab(a+b)\\8. a^3 + b^3 = (a-b)(a^2 - ab + b^2)\\9. a^3 - b^3 = (a+b)(a^2 + ab + b^2)\\10. a^3 + b^3 +c^3-abc = (a+b+c)(a^2+b^2+c^2-ab-bc-ca)$
