Solving Quadratic Inequalities Algebraically | Level 1
With either -1 or 1 as leading coefficients and integer break points, these printable quadratic inequalities worksheets get high school students transforming quadratic inequalities into quadratic equations and factoring them to solve the inequality.
Solving Quadratic Inequalities Algebraically | Level 2
Triumph in solving quadratic inequalities whose leading coefficients are integers by finding the factors, equating them to zero, determining their roots, and finding the solution range in this compilation of quadratic inequalities worksheet pdfs.
Solving Quadratic Inequalities Algebraically | Level 3
Instruct high school students to express the quadratic inequalities in standard form by moving the expressions on one side and equating to 0, factor them, determine their roots, to find the critical point and figure out the solution interval.
Solving Quadratic Inequalities | Table Method
Factor the quadratic inequalities and list out the intervals in the table of signs. Take a test value from each interval and apply on both the factors. Complete the table with the resultant plus or minus sign. Select the solution range that satisfies the inequality.
Graphing and Solving Inequalities
Check if the quadratic inequality is inclusive or strict. Graph the parabola y = f(x) for the quadratic inequality f(x) ≤ 0 or f(x) ≥ 0. Find the vertex and identify the values of x for which the part of the parabola will either be negative or positive depending on the inequalities.
Graphing Quadratic Inequalities
High school students plot x-intercepts, figure out the axis of symmetry and the vertex of the parabola, determine the direction, and illustrate the inequality using dotted or solid lines. Shade the parabola below or above the x-axis, inside or outside the parabola based on the solution.
