Question

What should we write as the zero of the polynomial if this happens in the graph?? ​

Answer 1

Answer:

-1.65 is the zero of the polynomial, because the parabola intersects the x-axis at-1.65

Answer 2

Answer:

First verify the answer by solving numerically. Check if your graph is accurate.

Then if it's right, the zero may be in the form of a root. In this case it may be -√3 since it is -1.7 So write the answer as -1.7

Also write how you solved numerically to be safe

Tip: Use thin lines to be accurate in graphs

Hope this helped :)
