Answer:

3x² - [ 4xy² - { 6x²y - (9xy² - 4x²y )}]= 3x² - 13xy²+  10x²y

Step-by-step explanation:

3x² - [ 4xy² - { 6x²y - (9xy² - 4x²y )}]

= 3x² - [ 4xy² - { 6x²y - 9xy² + 4x²y}]

= 3x² - [ 4xy² - { 6x²y+ 4x²y  - 9xy² }]

= 3x² - [ 4xy² - {  10x²y  - 9xy² }]

= 3x² - [ 4xy² -  10x²y + 9xy²]

= 3x² - [ 4xy²  + 9xy²-  10x²y]

= 3x² - [  13xy²-  10x²y]

= 3x² - 13xy²+  10x²y
