Answer:
is the different of two squaresB .X⁴y³ — 100
D. 4x⁸y² - 49
Step-by-step explanation:
DoTS has a format of a²-b² from (a+b)(a-b). The middle term cancels itself out such that the answer has only two terms.
4x⁸y²-49 = (2x⁴y+7)(2x⁴y-7)
such that:
= 2x⁴y(2x⁴y-7) + 7(2x⁴y-7)
= 2x⁴y(2x⁴y) - 2x⁴y(7) + 7(2x⁴y) - 7(7)
= 4x⁸y² - 14x⁴y + 14x⁴y - 49
= 4x⁸y² - 49

Answer:
D. 4x⁸y² - 49
Step-by-step explanation:
DoTS has a format of a²-b² from (a+b)(a-b). The middle term cancels itself out such that the answer has only two terms.
4x⁸y²-49 = (2x⁴y+7)(2x⁴y-7)
such that:
= 2x⁴y(2x⁴y-7) + 7(2x⁴y-7)
= 2x⁴y(2x⁴y) - 2x⁴y(7) + 7(2x⁴y) - 7(7)
= 4x⁸y² - 14x⁴y + 14x⁴y - 49
= 4x⁸y² - 49
