<h2>Steps:</h2>
So firstly, I will be factoring by grouping. For this, factor x⁶ - 9x⁴ and -x² + 9 separately. Make sure that they have the same quantity on the inside of the parentheses:
Now, you can rewrite the equation as:
However, it's not completely factored. Next, we will apply the formula for the difference of squares, which is . In this case:
Next, we will apply the difference of squares once more with the second factor as such:
<h2>Answer:</h2>
<u>The factored form of this equation is: </u>
Answer: A. Zero
Step-by-step explanation: If the quadratic equation is incomplete, b will always equal 0.
