Answer 2

A) To complete the expression "2y^3 (...+...)" and make it equal to "6y^4 + 8y^3", we need to determine the missing terms.

Expanding the left side of the equation:

2y^3 (...+...) = 2y^3 + (...)

To make the equation equivalent, we need to add a term that results in a 6y^4. Since 2y^3 multiplied by 3y gives us 6y^4, the missing term should be 3y.

2y^3 + 3y = 6y^4 + 8y^3

B) Similarly, to complete the expression "(x^2 - x^3) ..." and make it equal to "2x^3 - ...":

Expanding the left side of the equation:

(x^2 - x^3) ... = x^2 - x^3 + ...

To make the equation equivalent, we need to subtract a term that results in a 2x^3. Since x^3 multiplied by 2 gives us 2x^3, the missing term should be 2.

x^2 - x^3 - 2 = 2x^3 - ...

Please note that the missing terms in both equations could vary, and these are just examples of terms that make the equations balance.
