Question

Julian fully simplifies this polynomial and then writes it in standard form. 4x2y2 – 2y4 – 8xy3 + 9x3y + 6y4 – 2xy3 – 3x4 + x2y2 If Julian wrote the last term as –3x4, which must be the first term of his polynomial in standard form? 4y4 6y4 –2xy3 –10xy3

Answer 1

  4x²y² - 2y⁴ - 8xy³ + 9x³y + 6y⁴ - 2xy³ - 3x⁴ + x²y²

= 5x²y² +4y⁴ - 10xy³ + 9x³y - 3x⁴      combined like terms

= -3x⁴ + 9x³y  + 5x²y²  - 10xy³ + 4y⁴     descending exponent order based on "x"

If Julian wrote his list in descending order based on "y", then the order would be reversed.

Answer:  4y⁴
