Verified answer

Answer:

• (a+b) (a-b) is the required answer .

Explanation:

According to the Question

we have to factories the given Equation

• a² - b²

It is a identity which can be written as

→ a² - b² = (a+b) (a-b)

• Hence, the required option is (1) (a+b) (a-b)

Additional Information !!

Some More identities!!

• (a + b)² = a² + b² +2ab

• ( a - b )² = a² + b² -2ab

• ( a² - b² ) = ( a - b ) ( a + b )

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

• (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)

Answer:

• a² - b² = (a+b)(a-b)
