Question

x^2y^2 + 5y^4" align="absmiddle" class="latex-formula"> from $2x^4-8x^2y^2-y^4$

Answer 1

Answer:

the answer to the question is 8x⁴- 5x²y² - 6y⁴  

Step-by-step explanation:

the normal way of using BODMAS is apply to all polynomial equations.

subtracting  -6x⁴- 3x²y² + 5y⁴ from 2x⁴ - 8x²y² - y⁴.

polynomial of the same degree is very easy to calculate. this equation is having the same degree of polynomial all through, therefore:

  Applying Bracket to the equation

   2x⁴ - 8x²y² - y⁴- ( -6x⁴- 3x²y² + 5y⁴)

  Open the bracket

   2x⁴ - 8x²y² - y⁴ +6x⁴+3x²y² - 5y⁴

  collects the likes terms

   2x⁴ +6x⁴- 8x²y² +3x²y² - 5y⁴  - y⁴

  The final answer is =

   8x⁴- 5x²y² - 6y⁴
