To solve the expression, let's combine like terms by adding the coefficients of the same variables.

Given:

(1/12x^4 + 6/7x^3 + 3/8x^2 + 5) + (-7/12x^4 + 5/8x^2 - 5)

First, let's add the coefficients of x^4.

The coefficient of x^4 in the first term is 1/12, and in the second term, it is -7/12. Adding these coefficients, we get -6/12x^4, which simplifies to -1/2x^4.

Next, let's add the coefficients of x^3.

The coefficient of x^3 in the first term is 6/7, and in the second term, it is 0 (since there is no x^3 term). So, the x^3 term remains 6/7x^3.

Now, let's add the coefficients of x^2.

The coefficient of x^2 in the first term is 3/8, and in the second term, it is 5/8. Adding these coefficients, we get 8/8x^2, which simplifies to x^2.

Finally, let's add the constant terms.

The constant term in the first term is 5, and in the second term, it is -5. Adding these constants, we get 0.

Therefore, the simplified expression is:

-1/2x^4 + 6/7x^3 + x^2 + 0

Simplified further, the expression becomes:

-1/2x^4 + 6/7x^3 + x^2
