Find The Square And Simplify Your Answer.\[$(3f + 4)^2\$\]

$$

Understanding the Problem

When dealing with algebraic expressions, it's essential to know how to simplify them, especially when they involve squaring a binomial. In this case, we're given the expression $(3f + 4)^2$ and asked to find its square and simplify the answer. To tackle this problem, we'll use the formula for squaring a binomial, which is $(a + b)^2 = a^2 + 2ab + b^2$.

Squaring the Binomial Expression

To square the binomial expression $(3f + 4)^2$, we'll apply the formula for squaring a binomial. Here, $a = 3f$ and $b = 4$. Plugging these values into the formula, we get:

$$(3f + 4)^2 = (3f)^2 + 2(3f)(4) + 4^2$$

Expanding the Terms

Now, let's expand the terms in the expression:

$$(3f)^2 = 9f^2$$

$$2(3f)(4) = 24f$$

$$4^2 = 16$$

Combining the Terms

Next, we'll combine the terms to simplify the expression:

$$(3f + 4)^2 = 9f^2 + 24f + 16$$

Simplifying the Expression

The expression $9f^2 + 24f + 16$ is already simplified, but we can rewrite it in a more compact form:

$$(3f + 4)^2 = 9f^2 + 24f + 16$$

Understanding the Problem

In our previous article, we learned how to simplify the square of a binomial expression $(3f + 4)^2$. However, we know that practice makes perfect, and the best way to learn is by asking questions and getting answers. In this article, we'll address some common questions and concerns related to simplifying binomial expressions.

Q&A

Q: What is the formula for squaring a binomial?

A: The formula for squaring a binomial is $(a + b)^2 = a^2 + 2ab + b^2$. This formula is a powerful tool for simplifying binomial expressions.

Q: How do I apply the formula for squaring a binomial?

A: To apply the formula, simply substitute the values of $a$ and $b$ into the formula. For example, if we have the expression $(3f + 4)^2$, we would substitute $a = 3f$ and $b = 4$ into the formula.

Q: What if I have a binomial expression with a negative sign?

A: If you have a binomial expression with a negative sign, you can simply apply the formula as usual. For example, if we have the expression $(-3f + 4)^2$, we would substitute $a = -3f$ and $b = 4$ into the formula.

Q: How do I expand the terms in a binomial expression?

A: To expand the terms in a binomial expression, simply multiply each term by the other term. For example, if we have the expression $(3f + 4)^2$, we would multiply $3f$ by $4$ to get $12f$.

Q: What if I have a binomial expression with a variable in the exponent?

A: If you have a binomial expression with a variable in the exponent, you can simply apply the formula as usual. For example, if we have the expression $(3f^2 + 4)^2$, we would substitute $a = 3f^2$ and $b = 4$ into the formula.

Q: How do I combine like terms in a binomial expression?

A: To combine like terms in a binomial expression, simply add or subtract the coefficients of the like terms. For example, if we have the expression $3f^2 + 4f + 5f$, we would combine the like terms $4f$ and $5f$ to get $9f$.

Q: What if I have a binomial expression with a fraction?

A: If you have a binomial expression with a fraction, you can simply apply the formula as usual. For example, if we have the expression $(\frac{3f}{2} + 4)^2$, we would substitute $a = \frac{3f}{2}$ and $b = 4$ into the formula.
