It has already been shown (Art. 46), that, (a + b)2 = a2 + 2ab + b2 ; that is, The square of a binomial is equal to the square of the first term plus twice the product of the first term by the second, plus the square of the second.

...third forms, we see that the first member in each contains two terms of the square of a binomial, viz : the square of the first term plus twice the product of the 2nd term by the first. If, then, we take half the coefficient of x, viz : p, and square it, and add... | |

...by x + a, we shall have (x + a)3 = x3 + 2 ax + a' ; that is, the square of a binomial, is made up of the square of the first term, plus twice the product of the two terms, plus the square of the last term. This suggests the rule for extracting the square root... | |
