Question

factorise (a+0.2) (a²-0.2a+0.004)​

Answer 1

Answer:

Hii

Step-by-step explanation:

As we know that a³+b³ = (a+b)(a²-ab+b²)

Here a= a & b = 0.2a

= ( a + 0.2 ) ( a² - 0.2a + 0.004 )

= ( a + 0.2 ) ( a² + 0.004 - 0.2a )

= ( a + 0.2) ( (a)² + (0.2)² - ( a×0.2)

= a³ + 0.2³

Hope it help u
