WebCompleting the square method is a technique for find the solutions of a quadratic equation of the form ax^2 + bx + c = 0. This method involves completing the square of the quadratic expression to the form (x + d)^2 = e, where d and e are constants. WebTo find interval notation for a set of numbers, identify the minimum and maximum values of the set, and then use the appropriate symbols to represent the set. To express a set of …

2.6: Solving Absolute Value Equations and Inequalities
WebFirst, let us clear out the "/3" by multiplying each part by 3. Because we are multiplying by a positive number, the inequalities don't change: −6 < 6−2x < 12. Now subtract 6 from each part: −12 < −2x < 6. Now divide each part by 2 (a positive number, so again the inequalities don't change): −6 < −x < 3. WebUse interval notation to describe sets of numbers as intersections and unions. When two inequalities are joined by the word and, the solution of the compound inequality occurs when both inequalities are true at the same time. It is the overlap, or intersection, of the solutions for each inequality.
