Step-by-step explanation:

Answer 2

Answer:

Algebra Formula

a² – b² = (a-b)(a+b)

a² – b² = (a-b)(a+b)(a+b)² = a² + 2ab + b²

a² – b² = (a-b)(a+b)(a+b)² = a² + 2ab + b²(a-b)² = a² – 2ab + b²

a² – b² = (a-b)(a+b)(a+b)² = a² + 2ab + b²(a-b)² = a² – 2ab + b²a² + b² = (a-b)² +2ab.

a² – b² = (a-b)(a+b)(a+b)² = a² + 2ab + b²(a-b)² = a² – 2ab + b²a² + b² = (a-b)² +2ab.(a+b+c)² = a²+b²+c²+2ab+2ac+2bc.

a² – b² = (a-b)(a+b)(a+b)² = a² + 2ab + b²(a-b)² = a² – 2ab + b²a² + b² = (a-b)² +2ab.(a+b+c)² = a²+b²+c²+2ab+2ac+2bc.(a-b-c)² = a²+b²+c²-2ab-2ac+2bc.

a² – b² = (a-b)(a+b)(a+b)² = a² + 2ab + b²(a-b)² = a² – 2ab + b²a² + b² = (a-b)² +2ab.(a+b+c)² = a²+b²+c²+2ab+2ac+2bc.(a-b-c)² = a²+b²+c²-2ab-2ac+2bc.a³-b³ = (a-b) (a² + ab + b²)

a² – b² = (a-b)(a+b)(a+b)² = a² + 2ab + b²(a-b)² = a² – 2ab + b²a² + b² = (a-b)² +2ab.(a+b+c)² = a²+b²+c²+2ab+2ac+2bc.(a-b-c)² = a²+b²+c²-2ab-2ac+2bc.a³-b³ = (a-b) (a² + ab + b²)a³+b³ = (a+b) (a² – ab + b²)

Step-by-step explanation:

Taking LHS of the identity:

(a + b)

2

This can also be written as:

= (a + b) (a + b)

Multiply as we do multiplication of two binomials and we get:

= a(a + b) + b(a + b)

= a

2

+ ab + ab + b

2

Add like terms and we get:

= a

2

+ 2ab + b

2

Rearrange the terms and we get:

= a

2

+ b

2

+ 2ab

Hope this helps u.
