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

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.

Rewrite the following quadratic functions in intercept or factored form. show your work. y = x^2 + 7x + 10
