Разложим методом группировки:
Вынесем общий множитель у 7а и а2=а(7+а)
Вынесем общий множитель у -7b и -аb=-b(7+a)
Видим то что у них общая скобка следовательно(7+а)*(а-b)
Это и есть ответ

Alex Prior, a 13-year old singer and composer from the U.K. of Russian descent and a great-great-grandson of Konstantin Stanislavsky, will perform his own vocal cycle based on “Pokayannye” penitential verses on Wednesday. The concert is being held as part of the Star of Bethlehem Christmas Festival held in St. Petersburg between Jan 9-19.

The penitential verse cycle called “Primi mya pustynya” was written by Russian monks in the 17th century and presents not only religious but also philosophical, secular thoughts about life and its meaning. Prior began learning to read ancient Russian Orthodox texts in February 2006 at lessons given by Albina Kruchinina, his teacher at the St. Petersburg State Conservatory.

“I was deeply impressed by these quiet but very intense words. I enjoy the special melody of Church Slavonic language, which such distinguished Russian composers as Nikolai Rimsky-Korsakov and Modest Mussorgsky used in their compositions,” said Prior.

Prior is also writing an all-night vigil that is, when finished, to be blessed by the Russian patriarch Alexy II.

“You need to be very careful when writing religious music,” Prior said. “It is very important to pick up the church acoustics.”

The child prodigy said that besides the all-night vigil, he is working on a number of other compositions. Among them is a new opera, “Beowulf”, written in Old English, which he also enjoys.

“Prior’s compositions are one of the most successful and profound examples of modern sacred music that accurately reproduce the emotional connotations of the text,” said Yekaterina Smirnova, director of the Star of Bethlehem Festival. “In my opinion, in his creative work, Prior has inherited the best Russian musical traditions of ‘Khovanshchina’ and ‘Boris Godunov’ by Mussorgsky. Prior’s penitential verses have great potential and can be preformed as separate opera pieces. I am sure they will take a significant place among the best modern compositions of sacred music.”

Prior’s concerto for piano was performed in St. Petersburg in September at the St. Petersburg State Academic Cappella to an overcrowded hall. In June 2007, Prior’s ballet, “Mowgli,” will be staged by Natalia Kasatkina and Vladimir Vassiliyev and presented by the Moscow State Classical Ballet at the Kremlin Palace. On Wednesday, besides Prior’s music, the concert will feature religious compositions by Andrei Petrov, Grigory Korchmar, Igor Drukh, Boris Arkhimandritov, and Anton Lubchenko
