Σελίδα 19 - Divide the first term of the dividend by the first term of the divisor.
Σελίδα 25 - The square root of a number is one of the two equal factors of the number.
Σελίδα 18 - To divide a polynomial by a monomial, divide each term of the polynomial by the monomial: (Sab — 12ac) -i- 4a = 36 — 3c.
Σελίδα 149 - If the product of two numbers is equal to the product of two others, either two may be made the extremes of a proportion and the other two the means. For, if ad = be, then, dividing by bd, ad_ be bd~bd' ac or j- — -
Σελίδα 349 - Form all the possible products of n elements each that can be formed by taking one, and only one, element from each row, and one, and only one, element from each column...
Σελίδα 151 - In a series of equal ratios, the sum of the antecedents is to the sum of the consequents as any antecedent is to its consequent.
Σελίδα 167 - ... 16. The volume of a sphere varies as the cube of its diameter. Compare the volume of a sphere...
Σελίδα 149 - The equation ad = be gives a — -£, b = — ; so that an d с extreme may be found by dividing the product of the means by the other extreme ; and a mean may be found by dividing the product of the extremes by the other mean.
Σελίδα 84 - This is called completing the square. The second step is to extract the square root of each member of the resulting equation. The third step is to reduce the two resulting simple equations. (1) Solve the equation x2 — 8 x — 20.
Σελίδα 148 - We then write a:b = c:d, and read this, the ratio of a to b equals the ratio of c to d, or a is to b as c is to d.
