An optimal 3-point quadrature formula of closed type is derived. The obtained optimal quadrature formula has better estimations of error than the well-known Simpson's formula. A few error inequalities for this formula are established.

Key words: Optimal quadrature formula, error inequalities, Ostrowski-like inequalities.

Se establece una fórmula de cuadratura óptima de 3 puntos de tipo cerrado. Dicha fórmula mejora la estimación de error de la bien conocida fórmula de Simpson. Se establecen algunas desigualdades de error para esta fórmula.

Palabras clave: Fórmula de cuadratura óptima, desigualdades de error, desigualdades de tipo de Ostrowski.
