Solution Steps

To collect like terms, we need to combine the coefficients of the same powers of x x . In this case, we have terms with x3 x^3 and x2 x^2 . We will sum the coefficients of x3 x^3 and x2 x^2 separately.

Step 1: Combine Like Terms for x3 x^3

We start with the terms involving x3 x^3 : 14x3+38x3+116x3 \frac{1}{4} x^3 + \frac{3}{8} x^3 + \frac{1}{16} x^3 Calculating the coefficients: 14+38+116=1116 \frac{1}{4} + \frac{3}{8} + \frac{1}{16} = \frac{11}{16} Thus, the combined term for x3 x^3 is: 1116x3 \frac{11}{16} x^3

Step 2: Combine Like Terms for x2 x^2

Next, we combine the terms involving x2 x^2 : x216x2 -x^2 - \frac{1}{6} x^2 Calculating the coefficients: 116=6616=76 -1 - \frac{1}{6} = -\frac{6}{6} - \frac{1}{6} = -\frac{7}{6} Thus, the combined term for x2 x^2 is: 76x2 -\frac{7}{6} x^2

Step 3: Write the Final Expression

Combining both results, we have: 1116x376x2 \frac{11}{16} x^3 - \frac{7}{6} x^2

Final Answer

1116x376x2 \boxed{\frac{11}{16} x^3 - \frac{7}{6} x^2}
