Question

3x-2y amd 4y²+2x³ multiply​

Answer 1

Answer:

The value of expression $(3x-2y)(4y^{2} +2x^{3})$ is $12xy^{2} +6x^{4} -8y^{3} -4x^{3}y$.

Step-by-step explanation:

Given : $(3x-2y)(4y^{2} +2x^{3})$

To find : The value of the above expression.

Solution :

• The given expression is $(3x-2y)(4y^{2} +2x^{3})$.
• We have to multiply the given brackets in the expression.
• Multiplication is one of the important arithmetic operation of mathematics among division, multiplication, addition and subtraction.
• In multiplication, "-ve*+ve=-ve" and "-ve*-ve=+ve".
• So, the given expression is,

  $(3x-2y)(4y^{2} +2x^{3})$ = $3x(4y^{2} +2x^{3} )-2y(4y^{2} +2x^{3} )$

                             = $12xy^{2} +6x^{4} -8y^{3} -4x^{3}y$

• ∴ The value of expression $(3x-2y)(4y^{2} +2x^{3})$ is $12xy^{2} +6x^{4} -8y^{3} -4x^{3}y$.
