Question

Divide (a² -b²) by (a+b)​

Answer 1

( a- b ) will be the answer

Step-by-step explanation:

( a^ - b^ )

by using identity

a^ - b^ = ( a+ b ) ( a- b)

when we divide it by (a + b )

we get

( a - b )

Answer 2

Answer:

a-b

Step-by-step explanation:

$a {}^{2} - b {}^{2} = a + b \times a - b \\ a + b \times a - b \div a + b \\ a - b$

now a+b÷a+b is 1
