2x2+2x-4=0

Short Answer

Expert verified

The solutions to the equation 2x2+2x-4=0 are x=-2,1

Step by step solution

01

Step 1. Given Information.

The solutions to the given equation are to be determined using the related graph: 2x2+2x-4=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 1 and -2.

Hence the solutions to the equation 2x2+2x-4=0are x=-2,1.

03

Step 3. Conclusion.

Therefore, the solutions to the equation 2x2+2x-4=0 are x=-2,1.
