P(x) = x3 - 3x2 + 2x - 5; Is there a real zero between 2 and 3?

P(x) = x4 + 2x3 + 2x2 - 5x + 3; Is there a real zero between 0 and 1?

P(x) = x3 - 2x2 - 5; Is there a real zero between -1 and -2?

Find the upper and lower bounds for the following polynomials.

P(x) = x3 - x2 + x - 2

P(x) = x3 + 2x2 - 4
