(

Answer 1

Answer:

the answer will be 8x square -15y square +xy

Step-by-step explanation:

so first you have to multiply 4x with 2x-3y then you have multiply 5y with 2x-3y after it will become 8x square -12xy +10 xy -15y square +3xy ,solve the rest...then the main answer will be 8x square -15y square +xy :) hope it helped you !

Answer 2

Given: (4x + 5y) (2x - 3y) + 3xy

To find: Expansion and Simplification

Solution:

(4x + 5y) (2x - 3y) + 3xy

= 8x² - 12xy + 10xy - 15y² + 3xy    (First solving the brackets)

= 8x² - 15y² + 10xy + 3xy - 12xy   (Arranging according to their variables)

= 8x² - 15y² + 13xy - 12xy        (Step-by-step calculation of variables)

= 8x² - 15y² + xy

= 8x² + xy - 15y²

Answer: 8x² + xy - 15y²
