Answer 1

Answer:Method to do :

1st into last method , by breaking the

middle term into two .

or,

According to ( a² + b²)

Formula :

( a + b²) = ( a + b)² - 2ab

( a² - b²) = ( a+ b) ( a - b)

Solution :

25a² -30a + 9

according To formula , ( a ² + b²)

(5a)² + ( 3)² - 30a

( 5a - 3) ² + 2.5a.3 - 30a

( 5a + 3)² +30a -30a

( 5a + 3)²

( 5a + 3) ( 5a - 3) Answer
