Chapter 6: Q16. (page 297)

Use the related graph of each equation to determine its solutions.

-2x2-x+6=0

Short Answer

Expert verified

The solutions to the equation -2x2-x+6=0 are x=-2,1.5.

Step by step solution

01

Step 1. Given Information.

The solutions to the given equation are to be determined using the related graph: -2x2-x+6=0

02

Step 2. Explanation.

A quadratic equation has a real solution where the graph of the related function crosses or touches the x-axis.

From the given graph, the function crosses the x axis at -2 and 1.5.

Hence the solutions to the equation -2x2-x+6=0 are x=-2,1.5.

03

Step 3. Conclusion.

Therefore, the solutions to the equation -2x2-x+6=0 are x=-2,1.5.
