The Deep Dive
To simplify the expression \( \frac{8 x^{3}-3 x-6 x^{4}-2 x^{2}-1}{3 x+4} \), we first rearrange the terms in descending order of the power of \( x \): \[ \frac{-6 x^{4} + 8 x^{3} - 2 x^{2} - 3 x - 1}{3 x + 4} \] Next, we can use polynomial long division to divide the numerator by the denominator, \( 3x + 4 \). As we perform the division step by step, we start by dividing the leading term of the numerator by the leading term of the denominator. 1. Divide \( -6x^4 \) by \( 3x \) to get \( -2x^3 \). 2. Multiply \( -2x^3 \) by \( 3x + 4 \) to obtain \( -6x^4 - 8x^3 \). 3. Subtract this from the original numerator \( -6x^4 + 8x^3 - 2x^2 - 3x - 1 \) to yield \( 16x^3 - 2x^2 - 3x - 1 \). 4. Repeat the process for \( 16x^3 \) divided by \( 3x \) to get \( \frac{16}{3}x^2 \). 5. Continuing this iterative process allows us to simplify further until we reach a remainder. Finally, the complete division provides us with the quotient, which simplifies until we have a polynomial outcome plus a remainder divided by \( 3x + 4 \). To sum it up, the solution can be expressed as: \[ -2x^3 + \frac{16}{3}x^2 + ... + \text{(remainder)} \] By keeping track of each step, you can simplify higher degree polynomial fractions more confidently!
