To add the given algebraic expression,
(1/12X^4 + 6/7X^3 + 3/8X^2 + 5) + (-7/12X^4 + 5/8X^2 - 5),
we need to combine like terms and simplify.
First, let's combine the terms with the same variable exponent:
(1/12X^4 - 7/12X^4) + (6/7X^3) + (3/8X^2 + 5/8X^2) + (-5).
Subtracting the terms with the same variable exponent (X^4), we get:
(-6/12X^4) + (6/7X^3) + (8/8X^2) + (-5).
Next, let's simplify the expression further.
-6/12X^4 can be simplified as -1/2X^4, since both the numerator and denominator are divisible by 6.
8/8X^2 simplifies to 1X^2 or simply X^2.
Now we have:
-1/2X^4 + 6/7X^3 + X^2 - 5.
So, the simplified expression after addition is:
-1/2X^4 + 6/7X^3 + X^2 - 5.
