To multiply the polynomials (b+8)(3b-6), we can use the distributive property.
(b+8)(3b-6) = (b)(3b) + (b)(-6) + (8)(3b) + (8)(-6)
Simplifying this further:
= 3b² - 6b + 24b - 48
= 3b² + 18b - 48
Therefore, the simplified product of the polynomials is 3b² + 18b - 48.
(b+8)(3b-6) = (b)(3b) + (b)(-6) + (8)(3b) + (8)(-6)
Simplifying this further:
= 3b² - 6b + 24b - 48
= 3b² + 18b - 48
Therefore, the simplified product of the polynomials is 3b² + 18b - 48.

To multiply the polynomials (x^2y+2)(x^2−y), we can use the distributive property.
(x^2y+2)(x^2−y) = (x^2y)(x^2) + (x^2y)(-y) + (2)(x^2) + (2)(-y)
Simplifying this further:
= x^4y - xy^2 + 2x^2 - 2y
Therefore, the product of the polynomials (x^2y+2)(x^2−y) is x^4y - xy^2 + 2x^2 - 2y.
(x^2y+2)(x^2−y) = (x^2y)(x^2) + (x^2y)(-y) + (2)(x^2) + (2)(-y)
Simplifying this further:
= x^4y - xy^2 + 2x^2 - 2y
Therefore, the product of the polynomials (x^2y+2)(x^2−y) is x^4y - xy^2 + 2x^2 - 2y.

To simplify the expression x^3(2+y^5), we apply the distributive property:
x^3(2+y^5) = (x^3)(2) + (x^3)(y^5)
Simplifying further:
= 2x^3 + x^3y^5
Therefore, the expression equivalent to x^3(2+y^5) is 2x^3 + x^3y^5.
x^3(2+y^5) = (x^3)(2) + (x^3)(y^5)
Simplifying further:
= 2x^3 + x^3y^5
Therefore, the expression equivalent to x^3(2+y^5) is 2x^3 + x^3y^5.

To find the product (12x^2−3)(4y^3+5x^2) and demonstrate the Closure Property of multiplication of polynomials, we'll use the distributive property.
(12x^2−3)(4y^3+5x^2) = (12x^2)(4y^3) + (12x^2)(5x^2) + (-3)(4y^3) + (-3)(5x^2)
Simplifying further:
= 48x^2y^3 + 60x^4 - 12y^3 - 15x^2
Therefore, the product (12x^2−3)(4y^3+5x^2) is 48x^2y^3 + 60x^4 - 12y^3 - 15x^2. This demonstrates the Closure Property of multiplication of polynomials.
(12x^2−3)(4y^3+5x^2) = (12x^2)(4y^3) + (12x^2)(5x^2) + (-3)(4y^3) + (-3)(5x^2)
Simplifying further:
= 48x^2y^3 + 60x^4 - 12y^3 - 15x^2
Therefore, the product (12x^2−3)(4y^3+5x^2) is 48x^2y^3 + 60x^4 - 12y^3 - 15x^2. This demonstrates the Closure Property of multiplication of polynomials.
