we have given the value of x,y and m .

m=5,x=3,y=8.

we need to find the value of expression mx-y.

we need to plug the respective values and solve.

Find each product.<br><br> 1. 2x(x^2-6x+3)<br><br> 2. 2a^2(5b^2 + 3ab + 6a + 1)
hoa [83]

Given:

The expressions are:

2x(x^2-6x+3)

2a^2(5b^2+3ab+6a+1)

To find:

The product of each expression.

Solution:

According to the distributive property of multiplication over addition, we get

a(b+c)=ab+ac

The first expression is:

2x(x^2-6x+3)

Using distributive property of multiplication over addition, we get

2x(x^2-6x+3)=(2x)(x^2)+(2x)(-6x)+(2x)(3)

2x(x^2-6x+3)=2x^3-12x^2+6x

Therefore, the product of 2x(x^2-6x+3) is 2x^3-12x^2+6x.

The second expression is:

2a^2(5b^2+3ab+6a+1)

Using distributive property of multiplication over addition, we get

2a^2(5b^2+3ab+6a+1)=(2a^2)(5b^2)+(2a^2)(3ab)+(2a^2)(6a)+(2a^2)(1)

2a^2(5b^2+3ab+6a+1)=10a^2b^2+6a^3b+12a^3+2a^2

Therefore, the product of 2a^2(5b^2+3ab+6a+1) is 10a^2b^2+6a^3b+12a^3+2a^2.
