- First find the value of a.
- Put a into the quadratic equation.
Do step 1 by taking 3 to the other side and simplifying for a. For example: a= 32/3 + 31/3 +3. This gives us: a=10.
Do step 2 by putting the value of a into the second equation. This gives us:103 +9(102)+ 18(10)
Then solve the answer will be 1000+900+180 which gives 2080
