Q.15. - Precalculus Enhanced with Graphing Utilities

Question

In Problems 5–16, use a graphing utility to approximate the real solutions, if any, of each equation rounded to two decimal places. All solutions lie between - 10 and 10.$x^4- 5x^2 + 2x + 11 = 0$

Step-by-Step Solution

Answer

 There is no solution.$\mathrm{No}\hspace{0.17em}\mathrm{Solution}\hspace{0.17em}\mathrm{for}\hspace{0.17em}x\in \mathrm{ℝ}$

Step 1.Given equation

$x^4- 5x^2 + 2x + 11 = 0$

Step 2. Graph and X- intercepts

As graph is not cutting x-axis that is why there is no real solution
