Question

Find the product of (7p4+q)(49p8-7p4 q+q2) using suitable identity

Answer 1

Hi ,

******************

we know the algebraic identity,

( a + b ) ( a² - ab + b² ) = a³ + b³

********************************

( 7p⁴ + q ) ( 49p^8 - 7p⁴q + q² )

= ( 7p⁴ + q ) [ ( 7p⁴ )² - 7p⁴ × q + q² ]

= ( 7p⁴ )³ + q³

= 343p^8 + q³

I hope this helps you.
