HEY BUDDY!!!

HERE IS YOUR 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

HOPE THIS WILL HELP YOU..

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

(x+y+z)^{2} = x^{2} + y^{2} + z^{2} + 2xy + 2zy + 2zx

(x+y)^{3} = x^{3} + y^{3} + 3xy(x+y)

(x-y)^{3} = x^{3} - y^{3} - 3xy(x-y)

x^{3} +  y^{3} + z^{3} - 3xyz = (x+y+z)(x^{2}+y^{2}+z^{2}-xy-yz-zx )
