What are the roots of x cubed - 7*x squared + 13x-6
1 answer:
The roots of x^3 - 7x^2 + 13x - 6 are 0.697, 2 and 4.303
<h3>How to determine the roots?</h3>The expression is given as:
x^3 - 7x^2 + 13x - 6
Express as a function
f(x) = x^3 - 7x^2 + 13x - 6
Next, we plot the graph of the function f(x) (see attachment)
From the attached graph, we have the zeros to be:
x = 0.697, 2 and 4.303
Hence, the roots of x^3 - 7x^2 + 13x - 6 are 0.697, 2 and 4.303
