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. WebTo solve a polynomial equation write it in standard form (variables and canstants on one side and zero on the other side of the equation). Factor it and set each factor to zero. Solve each factor.
