The sum of the first n natural numbers is 210. Find n.
Use the formula: n(n + 1)/2 = 210.
Multiply both sides by 2: n(n + 1) = 420.
Solve the quadratic equation: n² + n - 420 = 0.
n = 20 (since n must be positive).
A quadratic equation x² - 5x + 6 = 0 has roots. Find the roots.
Factor the equation: (x - 2)(x - 3) = 0.
Roots are x = 2 and x = 3.
