Expanding the Binomial Expression

Oct 13, 2025 by windailys.com 78 views

Understanding the Problem

When expanding a binomial expression, we can use the formula (a + b)^2 = a^2 + 2ab + b^2. In this case, we have (6p + 2)^2, where a = 6p and b = 2. To find the coefficient of the second term, we need to identify the term that corresponds to 2ab.

Expanding the Binomial Expression

Using the formula, we can expand (6p + 2)^2 as follows:

(6p + 2)^2 = (6p)^2 + 2(6p)(2) + 2^2

Simplifying the Expression

Now, let's simplify the expression by evaluating the terms:

(6p)^2 = 36p^2 2(6p)(2) = 24p 2^2 = 4

Combining the Terms

Now, let's combine the terms to get the expanded form of the trinomial:

(6p + 2)^2 = 36p^2 + 24p + 4

Identifying the Coefficient of the Second Term

The second term of the trinomial is 24p. To find the coefficient of this term, we need to identify the numerical value that multiplies the variable p. In this case, the coefficient is 24.

Conclusion

In conclusion, the coefficient of the second term of the trinomial (6p + 2)^2 is 24.
