She now began to read Euclids Elements, and proceeded in algebra as far as quadratic equations.
What does matter is thisI must ask you to tell me exactly why you wished me to work out that quadratic problem for you.
Since the fraction is infinite it cannot be commensurable and therefore its value is a quadratic surd number.
Another type of quadratic moment is supplied by the deviation-moments, or products of inertia of a distribution of matter.
The quadratic moments with respect to different planes through a fixed point O are related to one another as follows.
It is right, but too lengthy to be worth as much as a quadratic.
Following J. Plcker, we give an account of the lines of a quadratic complex that meet a given line.
1650s, "square," with -ic + obsolete quadrate "a square; a group of four things" (late 14c.), from Latin quadratum, noun use of neuter adjective quadratus "square, squared," past participle of quadrare "to square, set in order, complete" (see quadrant).

Relating to a mathematical expression containing a term of the second degree, such as x2 + 2. ◇ A quadratic equation is an equation having the general form ax2 + bx + c = 0, where a, b, and c are constants. ◇ The quadratic formula is x = -b ± √(b2 - 4ac)/2a. It is used in algebra to calculate the roots of quadratic equations.
