QUADRATIC EQUATIONS.203XIX. QUADRATIC EQUATIONS.339. A Quadratic Equation is an equation of the second degree (Art. 179), containing but one unknown quantity.A Pure Quadratic Equation is a quadratic equation involving only the square of the unknown quantity ;An Affected Quadratic Equation is a quadratic equation involving both the square and the first power of the unknown quantity ; as, 2x* - 3 x - 5 = 0.PURE QUADRATIC EQUATIONS.340. A pure quadratic equation may be solved by reducing it, if necessary, to the form x2 = a, and then extracting the square root of both members.5 a,"21. Solve the equation 3 x2 + 7 = + 35.Clearing of fractions, 12 x2 + 28 = 5 x2 +140.Transposing and uniting, 7 x2 = 112, or, x2 = 16 ;which is in the form x2 = a.Extracting the square root of both members, we havea = ±4. (Notes 1 and 2.)Note 1. The sign ± is placed before the result, because the square root of a number is either positive or negative (Art. 236).Note 2.
