(-3.562, 0); (0.562, 0)

#### Explanation:

${x}^{2} + 3 x - 2 = 0$

First find the vertex

$x = \frac{- b}{2 \times a} = \frac{_ 3}{2 \times 1} = \frac{- 3}{2} = - 1.5$

Take three values greater than and less than$- 1.5$

Plot the points on the graph. Locate the point where it cuts the x-axis.

The points are -

(-3.562, 0); (0.562, 0)
