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

Explanation:

x^2+3x-2=0x2+3x2=0

First find the vertex

x=(-b)/(2xxa)=(_3)/(2xx1)=(-3)/2=-1.5x=b2×a=_32×1=32=1.5

Take three values greater than and less than-1.51.5

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

The points are -

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