Abridged multiplication formulas with examples. Task 1
For calculation we will use the algorithm of the abridged multiplication formulae.
At the first stage of the calculation it is necessary to try to find one (or several) abridged multiplication formulae.
It is evident that this expression is the square of the sum of two expressions where:
According to the formula: The square of a sum of two expressions is equal to the square of the first, plus twice the product of the first and second, plus the square of the second.
