i need help with only part c ii. idk how to make it equal to the eqn of the graph.

Varun Rawat answered this

0.5 [x^{2} + \frac{5}{x} - 4 x] = 0 \Rightarrow x^{3} + 5 - 4 x^{2} = 0 Consider p (x) = x^{3} - 4 x^{2} + 5

GRAPH of p(x) :

Now, from the graph, we see that the solution of the given cubic equation is, x = - 1; 1.4 and 3.6
