S(3) = 2(3)^2 + 3(3) + 1 = 2(9) + 9 + 1 = 18 + 9 + 1 = 28 - Blask
Understanding the Quadratic Expression: S(3) = 2(3)² + 3(3) + 1 = 28
Understanding the Quadratic Expression: S(3) = 2(3)² + 3(3) + 1 = 28
When solving quadratic expressions, one common form students and math enthusiasts encounter is S(n) = an² + bn + c. A recent example that illustrates this pattern clearly is S(3) = 2(3)² + 3(3) + 1, which simplifies step-by-step to yield the final result of 28. Let’s break down this calculation and explore what makes this quadratic expression meaningful.
Understanding the Context
Breaking Down the Expression: S(3) = 2(3)² + 3(3) + 1
This quadratic function fits the standard form:
S(n) = an² + bn + c
where:
- a = 2
- b = 3
- c = 1
When evaluating S(3), we substitute n = 3 into the expression:
S(3) = 2(3)² + 3(3) + 1

Key Insights
-
Calculate the squared term:
(3)² = 9
Then multiply by coefficient a:
2 × 9 = 18 -
Evaluate the linear term:
3 × 3 = 9 -
Add all parts:
18 + 9 + 1 = 28
Thus, S(3) = 28, confirming the complete simplification.
