Question

simplify:2x²y-[4y²x-{3x²y-(4x²y-2xy² please explain step by step​

Answer 1

Answer:

(2x²y-3x²y-4x²y) - 2xy²

Step-by-step explanation:

first step is that you have to check the powers and variables are in a same order like example : 4x²- 8xyz-15 - 5xyz-2x²-6 simplification is

(4x²- 2x²) -(8xyz - 5xyz) - (15-6) = (2x² - 3xyz - 9)

second step if it is in the symbol minus (-) than you have to minus the expressions

third step you should bracket them

Answer 2

Answer:

      x²y - 2xy²

Step-by-step explanation:

  2x²y - [4y²x - { 3x²y -( 4x²y - 2xy² )} ]​

= 2x²y - [4y²x - { 3x²y - 4x²y + 2xy²} ]​

= 2x²y - [4y²x - 3x²y + 4x²y - 2xy² ]​

= 2x²y - 4y²x + 3x²y - 4x²y + 2xy²

= 2x²y + 3x²y - 4x²y - 4y²x + 2xy²

= x²y - 2xy²
