Verified

Answer

The solutions to the equation $2 x^{2} + 2 x - 4 = 0$ are x=-2,1

1Step 1. Given Information.

The solutions to the given equation are to be determined using the related graph: $2 x^{2} + 2 x - 4 = 0$

2Step 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 $2 x^{2} + 2 x - 4 = 0$ are x=-2,1.

3Step 3. Conclusion .

Therefore, the solutions to the equation $2 x^{2} + 2 x - 4 = 0$ are x=-2,1.
