Q.16. - 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.$-3x^4 + 8x^2 - 2x - 9 = 0$

Step-by-Step Solution

Answer

$There are no \mathrm{Solution}\hspace{0.17em}\mathrm{for}\hspace{0.17em}x\in \mathrm{ℝ}$

Step 1.Given equation

$-3x^4+8x^2-2x-9=0$

Step 2. Graph and X-intersection

Graph is not intersecting x- axis anywhere so the solution of this equation has no real value.
