How to Solve: Step-by-Step—Why It Matters Beyond the Formula
To determine $ p(3) $, begin with the general quadratic form:
$$ p(x) = ax^2 + bx + c $$
Using the conditions $ p(0) = 5 $, substitute $ x = 0 $:
$$ p(0) = c = 5 $$
Thus, $ c = 5 $.

Next, apply $ p(1) = 3 $, where $ x = 1 $:
$$ p(1) = a(1)^2 + b(1) + 5 = a + b + 5 = 3 \Rightarrow
