Answer

The answer is \( x^{6} + 2x^{4} - 3 \), choice b.

Solution

To divide the expression \(\frac{4 x^{8}+8 x^{6}-12 x^{2}}{4 x^{2}}\), you can simplify each term in the numerator by dividing by \(4x^{2}\): \[ \frac{4x^8}{4x^2} = x^{6} \] \[ \frac{8x^6}{4x^2} = 2x^{4} \] \[ \frac{-12x^2}{4x^2} = -3 \] Combining these results gives: \[ x^{6} + 2x^{4} - 3 \] **Answer:** **b.)** \( x^{6}+2 x^{4}-3 \)

The Deep Dive

First, let's simplify the expression \( \frac{4 x^{8}+8 x^{6}-12 x^{2}}{4 x^{2}} \) by dividing each term in the numerator by \( 4 x^{2} \): 1. \( \frac{4 x^{8}}{4 x^{2}} = x^{6} \) 2. \( \frac{8 x^{6}}{4 x^{2}} = 2 x^{4} \) 3. \( \frac{-12 x^{2}}{4 x^{2}} = -3 \) Putting it all together, we have: \( x^{6} + 2 x^{4} - 3 \) So the correct answer is: **b.) \( x^{6}+2 x^{4}-3 \)** --- Did you know that polynomial long division isn't just a math trick for classrooms?
