Factor and Solve Polynomial Equations
Recall how to Factor Quadratic Equations…
You are building a bin to hold cedar mulch for your garden. The
bin will hold 162 ft3 of mulch. The dimensions of the bin are x ft.
by 5x – 6 ft. by 5x – 9 ft. How tall will the bin be?
The cubic polynomial P(x) has a zero of multiplicity one at x = 1, a zero of multiplicity two at x = 2, and P(-1) =
2. Determine P(x) and sketch the graph.
Sketch a graph of a polynomial P(x) that has a zero of multiplicity one at x=1, a zero of multiplicity two at x = 1, a zero of multiplicity three at x = -3, and satisfies P(x)→ - ∞ as x → ∞, and P(x) → - ∞ as x → - ∞.
