Question

Factorise
(a+b)² - a² + b² ​

Answer 1

Answer:

The factors of the given expression is

2b(a + b)

step by step explanation

We need to Factorise

(a+b)² - a² + b²

As we know

(a+b)² = a²+ b² +2ab

Now,

= (a+b)² - a² + b²

= a²+ b² +2ab - a²+ b²

= 2ab+ 2b²

= 2b(a + b)

Answer 2

Answer:

${(a + b)}^{2} - { a}^{2} + {b}^{2}$

${a}^{2} + {b}^{2} + 2ab - {a}^{2} + {b}^{2}$

$2 {b}^{2} + 2ab$

$b(2a + b)$
