Question

Find the product1/2 12 y 3 - 8O-YA + 4yy + 4y23+ 4

Answer 1

Given data:

The given expression is -1/2 y(2y^3 -8).

The given expression can be written as,

`\begin{gathered} -(1)/(2)y(2y^3-8)=-(1)/(2)y(2y^3)+(1)/(2)y(8) \\ =-y^4+4y \end{gathered}`

Thus, the correct option is first -y^4 +4y.
