Write in factored form by factoring out the greatest common factor. $16 z^{4}+24 z^{2}$

Short Answer

Expert verified

8z^2(2z^2 + 3)

Step by step solution

- Identify the Greatest Common Factor (GCF)

First, identify the greatest common factor of the given terms. The terms are 16z^4 and 24z^2. The coefficients are 16 and 24, and the variables are z^4 and z^2. The GCF of 16 and 24 is 8. The GCF of z^4 and z^2 is z^2. Therefore, the GCF of 16z^4 and 24z^2 is 8z^2.

- Factor out the GCF

Next, factor out the GCF from each term. Divide each term by the GCF (8z^2) and write the expression in factored form: \[ \frac{16z^4}{8z^2} + \frac{24z^2}{8z^2} = 2z^2 + 3 \].

- Write the Factored Form

Finally, write the original expression as the product of the GCF and the simplified expression from step 2: \[ 8z^2(2z^2 + 3) \].

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Greatest Common Factor

The greatest common factor (GCF) is crucial in simplifying polynomials. When you look at a polynomial like $16z^4 + 24z^2$, you need to find the GCF of both the coefficients and the variable parts. Here, the coefficients are 16 and 24. The GCF of 16 and 24 is 8. For the variables, you have $z^4$ and $z^2$. The largest power of $z$ that is common in both terms is $z^2$. So, the GCF of the polynomial $16z^4 + 24z^2$ is $8z^2$. This simplifies the polynomial and makes it easier to factor out and solve problems.

Factored Form

Writing an expression in its factored form involves using the GCF you found. For our exercise, we found the GCF to be $8z^2$. To write $16z^4 + 24z^2$ in factored form, you need to factor $8z^2$ out of each term.
Here's how it looks step by step:

Divide each term by the GCF $8z^2$:
\[ \frac{16z^4}{8z^2} + \frac{24z^2}{8z^2} \]
Simplify inside the parentheses: \[2z^2 + 3\]
Write the original polynomial as the product: \[8z^2(2z^2 + 3)\]

This shows each term divided by the GCF, resulting in a much simpler polynomial.

Polynomial Division

Polynomial division is often necessary when factoring. It involves dividing each term in the polynomial by the GCF. For our example, we had: \[16z^4 + 24z^2\]When we divide by $8z^2$:

\[ \frac{16z^4}{8z^2} = 2z^2\]
\[ \frac{24z^2}{8z^2} = 3 \]

This division simplifies the polynomial.

Understanding polynomial division helps recognize patterns and solve higher-level problems. Practice this skill to become proficient in simplifying and factoring more complex polynomials.
