How do I do this?

Show all work clearly and in order, and circle your final answers. Justify your answers alge- braically whenever possible; when you do use your calculator, sketch all relevant graphs and write down all relevant mathematics. 1. (1 point) The degree of f(x) = (x3 + 8x2 + 11x - 20) (x2 -3) is 2. (1 point) Factor f(x) = x3+4x2+ x -6. (Hint: f(-2) = 0)
