Step 1: First, divide the coefficient of the highest power of x in the numerator (42x^3) by the coefficient of x in the denominator (7x).
6x^2 = \frac{42x^3}{7x}
This gives us 6x^2.
Step 2: Next, subtract this result from the original fraction to find the remaining fraction.
\frac{42x^3 - 6x^2 \times 7x}{7x}
Final Answer
Therefore, none of the given answer choices is correct.
