Introduction

In algebra, multiplying and simplifying expressions is a crucial skill that helps us solve equations and manipulate mathematical statements. In this article, we will focus on multiplying and simplifying the expression (d+8)(d-8). This expression involves the product of two binomials, and we will use the distributive property to expand and simplify it.

Understanding the Distributive Property

The distributive property is a fundamental concept in algebra that allows us to expand and simplify expressions by multiplying each term in one expression by each term in another expression. In the case of the expression (d+8)(d-8), we will use the distributive property to multiply each term in the first binomial (d+8) by each term in the second binomial (d-8).

Multiplying the Binomials

To multiply the binomials (d+8) and (d-8), we will use the distributive property to expand and simplify the expression. We will multiply each term in the first binomial by each term in the second binomial, and then combine like terms.

import sympy as sp

d = sp.symbols('d')



expr = (d + 8) * (d - 8)



expanded_expr = sp.expand(expr)
simplified_expr = sp.simplify(expanded_expr)


print(simplified_expr)

Simplifying the Expression

After multiplying the binomials, we will simplify the expression by combining like terms. In this case, we will combine the terms with the variable d and the constant terms.

The Final Answer

The final answer is d^2 - 64.

Explanation

The expression (d+8)(d-8) can be simplified by multiplying each term in the first binomial by each term in the second binomial. This results in the expression d^2 - 8d + 8d - 64. Combining like terms, we get d^2 - 64.

Conclusion

In this article, we multiplied and simplified the expression (d+8)(d-8) using the distributive property. We expanded and simplified the expression by multiplying each term in the first binomial by each term in the second binomial, and then combined like terms. The final answer is d^2 - 64.
