Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
