Page 280 - ... graphs of the quadratic equation and the linear equation may be approximated and their coordinates taken as solutions, since the points lie on both curves. The simplest algebraic method is carried out by eliminating one of the variables. More specifically, we solve the linear equation for one variable in terms of the other, substitute this value in the quadratic equation, and solve the resulting quadratic equation in one variable. With these results substituted in the original linear equation,...

Page 245 - See how many times this trial divisor is contained in all of the dividend, excepting the right hand figure, and write the quotient as the next figure of the root, and also place it at the right of the trial divisor, to form a true divisor.
