WebAs has been noted, the easiest way to solve a polynomial inequality f ( x) < 0 (or f ( x) > 0) is to find the roots of the polynomial f, and then form a sign chart. I would like to mention the reason why sign charts work. WebSolving quadratics by completing the square.

WebOct 6, 2024 · Solve the given inequality. x2 − 2 x − 3 > 0 In this problem, we have the same asymptote as the previous two problems: x = 3. However, in this inequality, there are two roots, because there are two x values that make the numerator equal zero. x2 − 2 = 0 means that x2 = 2 and x = ± √2 ≈ ± 1.414 We can see these roots on the graph. cyclopithecus
