Answer 2

Answer:

Okay so it's just a try,

b) simplify:

( 3x + 5y )( 9x² - 15xy + 25y² )

= ( 3x + 5y )[ (3x)² - (3x) (5y) + (5y)² ]

= ( 3x )³ + ( 5y )³

= 27x³ + 125y³

so this is it.

c) factorize: x⁴ + 3x² + 4

= ( x² )² + 3( x² ) + 4

= ( x² )² + 4x² - x² + 4

= ( x² )² + 4x² + 4 - x²

= ( x² + 2 )² - x²

= ( x² + 2 - x )( x² + 2 + x )

so hope it maybe helpful!!
