Página 23 - The first method which suggests itself is one similar to that usually given to determine the coefficients of the equation whose roots are the squares of the differences of the roots of any given equation.
Página 13 - ... the first root is essentially positive. The second root, being equal to p, minus a quantity less than p, is essentially positive. Hence, in the fourth form, both roots are positive. See problems 14 and 15, Art. 212. REVIEW. — 215. Show that every quadratic equation has two roots, and only two. 216. To what is the sum of the roots equal? To what is the product equal?
Página 10 - REVIEW. — 80. To what is the square of the sum of two quantities equal ? 81.
Página 11 - What is the greatest common divisor of 918 and 5221 (251.) In the application of this rule to polynomials, some modification may become necessary. It may happen that the first term of the dividend is not divisible by the first term of the divisor. This may arise from the presence of a factor in the divisor which is not found in the dividend, and may therefore be suppressed. For, since the greatest common divisor of two quantities is only the product of their common factors, it cannot be affected...
Página 6 - The numbers over the questions are the numbers of the articles of Bourdon in which the answers are to be found ; and the numbers before them are those of the corresponding articles in Lacroix. Where the book does not contain the answer to the question, no number is placed.
Página 5 - PREFACE. THE French Algebras, so superior as books of instruction, are written in the form of a continuous treatise, without distinct divisions. The student is in consequence often at a loss to know what is to be carefully retained in the memory, and what may 3' be passed over more rapidly, as being intended only < for immediate explanation.
Página 9 - ART. 138. THEOREM. — If the same quantity be added to both terms of a proper fraction, the new fraction resulting will be greater than the first; but if the same quantity be added to both terms of an improper fraction, the new fraction resulting Witt be less than the first, Let - be a proper fraction, a being less than b. b Let m represent the quantity to be added to each term, then...
