Question

mulitiply (2y + 1); (y2 - 2y3 + 3y)​

Answer 1

Answer:-4y⁴+7y²+3y

Step-by-step explanation:Product of given polynomials

= ( 2y + 1 )(y²-2y³+3y)

=2y(y²-2y³+3y)+1(y²-2y³+3y)

= 2y³-4y⁴+6y²+y²-2y³+3y

= -4y⁴ +2y³-2y³+6y²+y²+3y

= -4y⁴+7y²+3y

Answer 2

$\bold{Question}$

mulitiply (2y + 1); (y2 - 2y3 + 3y)

$\bold{Solution}$

Product of given polynomials

$\bold{= ( 2y + 1)(y²-2y³+3y)}$

$\bold{=2y(y²-2y³+3y)+1(y²-2y²+3y)}$

$\bold{=-2y³-4y⁴+6y²+y²-2y³+3y }$

$\bold{=-4y* +2y³-2y³+6y²+y²+3y}$

$\bold{\red{= -4y⁴+7y²+3y}}$

hope it helps ☺️☺️
