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

Short answer

$Thereareno\mathrm{Solution}\hspace{0.17em}\mathrm{for}\hspace{0.17em}x\in \mathrm{ℝ}$

Step-by-step solution

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.
