(-3.562, 0); (0.562, 0)(−3.562,0);(0.562,0)
Explanation:
x^2+3x-2=0x2+3x−2=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
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)
