3-31.

Write down Liha's and Makulata's tile pieces as expressions.

Liha 3*x*^{2} + 2*x* + 8

Makulata 5*x*^{2} + 2

Now add the two together.

3*x*^{2} + 2*x* + 8 + 5*x*^{2} + 2 = 8*x*^{2} + 2*x* + 10

Add like terms and then simplify.

Write the two terms down as an expression.

Convert both fractions to a common denominator before combining like terms.
