Question

Based on the graph, what are the solutions of x3 + x2 – 9x – 9 = 0?

Answer 1

Can u put a picture of the problem

Answer 2

The solutions of given equation are -3, -1 and 3.

Explanation:

The given equation is

`x^3+x^2-9x-9=0`

The solution of above equation are the x-intercept of the polynomial

`P(x)=x^3+x^2-9x-9`

The graph of the polynomial P(x) is shown below.

From the graph it is clear that the graph intersect the x-axis at (-3,0), (-1,0) and (3,0). It means the x-intercepts of the polynomial P(x) are -3,-1 and 3.

Therefore the solutions of given equation are -3, -1 and 3.
