Question

(2y3+3y2-7)-(5+3y+y3)=3y2+y3-5y​

Answer 1

Ответ:

$3y {}^{2} + y {}^{3} - 5y$

Answer 2

It seems like you're trying to simplify the expression (2y^3 + 3y^2 - 7) - (5 + 3y + y^3). To do this, you can distribute the negative sign on the right side of the equation and then combine like terms:

(2y^3 + 3y^2 - 7) - (5 + 3y + y^3) = 2y^3 + 3y^2 - 7 - 5 - 3y - y^3

Now, combine the like terms:

(2y^3 - y^3) + (3y^2) + (-3y - 5 - 7)

Simplify each term further:

y^3 + 3y^2 - 3y - 5 - 7

Finally, combine the constants:

y^3 + 3y^2 - 3y - 12

So, the simplified expression is:

y^3 + 3y^2 - 3y - 12
