Master the art of solving quadratic inequalities using sign analysis, a powerful technique for determining solution intervals. this lesson delves into factoring, critical values, test points, and interval notation. Write the solution in interval notation. solution: step 1: write the quadratic inequality in standard form. the inequality is in standard form. \ (x^ {2} 6 x 8<0\) step 2: graph the function \ (f (x)=a x^ {2} b x c\) using properties or transformations. we will graph using the properties. \ (f (x)=x^ {2} 6 x 8\) look at \ (a\) in the equation. Use a sign graph to solve the inequality x 2 3x 10 > 0. because the left hand side can be factored, we can write the inequality as (x 5) (x 2) > 0. this inequality says that the product of x 5 and x 2 is positive. if both factors are negative or both are positive, the product is positive. Sign analysis is crucial in solving rational inequalities and quadratic inequalities, as it helps determine the solution set and the behavior of the inequality. This video introduces sign analysis as a method to solve single variable quadratic inequalities. this video was built as part of the learning resources provi.
