Question

give the right answer of formula image if you right i follow you and mark as brailint and if you wrong I report you and don't report me​

Answer 1

Answer:

Follow Me and Mark As Brainliest!!

Step-by-step explanation:

(a + b)² = a² + 2ab + b²

(a - b)² = a² – 2ab + b²

a² - b² = (a + b)(a – b)

a² + b² = No such Identity!!

(a + b)³ = a³ + b³ + 3ab (a + b)

(a - b)³ = a³ – b³ – 3ab (a – b)

a³ + b³ = (a + b) (a² - ab + b²)

a³ - b³ = (a – b) (a² + ab + b²)

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

Answer 2

Step-by-step explanation:

(a+b)²=a²+2ab+b²

(a-b)²=a²-2ab+b²

(a²-b²)=(a²+b)(a²-b)

(a²+b²) =___

(a+b)³=a³+b³+3ab(a+b)

(a-b)³=a³-b³-3ab(a-b)
