Good morning,
.
We add adding together two polynomials.
.
%28%285%2F4%29a%5E2-3a-1%2F2%29%2B%28%283%2F8%29a%5E2%2B%281%2F2%29a%2B2%29
.
Remember that we can only combine like terms (the same variable, raised to the same power.) We can combine the two a-squared terms by adding their coefficients (5/4 and 3/8), but they must have the same denominator. The fraction 5/4 is equivalent to 10/8, so 5/4+3/8 = 10/8+3/8 = 13/8.
.
%2813%2F8%29a%5E2-3a-1%2F2%2B%281%2F2%29a%2B2
.
We can combine the a-terms by adding their coefficients: -3a+(1/2)a = -(5/2)a.
.
%2813%2F8%29a%5E2-%285%2F2%29a-1%2F2%2B2
.
Finally, we can combine the constant terms: -(1/2)+2 = 3/2
.
%2813%2F8%29a%5E2=%285%2F2%29a%2B3%2F2
.
That's it. Feel free to email me if you have questions about the explanation.
