Chapter 1: Q 5. (page 51)

Use a graphing utility to approximate the real solution of the equation rounded to two decimal places .All solution lie between $- 10$ and $10$ .
Equation is $x^{4} - 5 x^{2} - 8 = 0$

Short Answer

Expert verified

The roots of the equation are $x = \sqrt{8} (\sqrt{8} = 2.62)$ and $x = \sqrt{13}, (\sqrt{13} = 3.60)$ $x = \sqrt{8} . (\sqrt{8} = 2.82), x = \sqrt{13} (\sqrt{13} = 3.60)$

Step by step solution

Step 1. Given information.

Consider the given equation $x^{4} - 5 x^{2} - 8 = 0$

Step 2. Find the root of the equation.

The root of the equation are.

$x^{4} - 5 x^{2} - 8 = 0 x^{2} (x^{2} - 5) = 0 x = \sqrt{8}, x = \sqrt{13}$

Step 3. Plot the graph.

The graph of the equation using graphic utility as shown below.

Equation $Y = x^{4} - 5 x^{2} - 8$
