Question

multiply (-3xy) and (-5y +2)​

Answer 1

• As per the data given in the question, we have to determine the multiplication of expression.

        Given data:- $(-3xy)$ and $(-5y+2)$.

        To find:- the multiplication of expression.

• Here, we will use the distributive property of multiplication:- It is the multiplication of a number by a sum is equal to the sum of the multiplications of this number by each one of the amounts to be added.

        $\Rightarrow (-3xy)\times(-5y+2)\\\Rightarrow (-3xy\times-5y-3xy\times2)\\\Rightarrow 15xy^{2}-6xy.$

        Hence the value will be $15xy^{2}-6xy.$

   

Answer 2

Given,

Multiply $(-3xy)$ and $(-5y+2)$

• By using distributive property of multiplication to solve the given expression,
• Distributive property of multiplication: The sum or difference of two numbers multiplied by a number is the sum or difference of the product of each number and the number and the number used to multiply.

So,

$(-3xy)\times(-5x+2)\\=-3xy\times-5y+2\times(-3xy)\\=15xy^{2} -6xy$

Therefore, the correct answer is $15xy^{2}-6xy$.
