Question

-3y (y⁴ + 2y³ - 5y²- y + 4)​

Answer 1

`\qquad\qquad\huge\underline{{\sf Answer}}♨`

Let's expand the given expression ~

`\qquad \sf  \dashrightarrow \: - 3y( {y}^(4) + 2 {y}^(3) - 5 {y}^(2) - y + 4)`

`\qquad \sf  \dashrightarrow \: ( - 3y \cdot {y}^(4) ) + ( - 3y \cdot2 {y}^(3) ) + ( - 3y \cdot - 5 {y}^(2) ) + ( - 3y \cdot - y) + ( - 3y \cdot4)`

`\qquad \sf  \dashrightarrow \: - 3{y}^(5) - 6{y}^(4) + 1 5 {y}^(3) + 3{y}^(2) - 12y`
