Answer 1

Answer:

• (a-b)^2=a^2+b^2-2ab
• (a+b)^2=a^2+b^2+2ab
• (a-b) (a+b)=(a^2-b^2)
• (a-b) ^3=(a-b)(a^2+b^2-2ab)
• (a+b)^3=(a+b)(a^2+b^2+2ab)
• a^2+b^2=(a+b)^2-2ab
• (x+a)(x+b)=x^2+(a+b) x+ab

etc...

Hope it will help you

Answer 2

Answer

(a + b)² = a² + 2ab + b²

(a – b)² = a² – 2ab + b²

a² – b² = (a + b)(a – b)

(x + a)(x + b) = x² + (a + b) x + ab

(a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca

(a + b)³ = a³ + b³ + 3ab (a + b)

(a – b)³ = a³ – b³ – 3ab (a – b)

a³ + b³ + c³ – 3abc = (a + b + c)(a² + b² + c² – ab – bc – ca)
