Finding the zeros of a polynomial function
WebJan 10, 2024 · We find three real zeros, x = 1 − √2 = − 0.414…, x = 1 + √2 = 2.414…, and x = 5, of which only the last two fall in the applied domain of [0, 10.07]. We choose x = 0, x = 3 and x = 10.07 as our test values and plug them into the function P(x) = − 5x3 + 35x2 − 45x − 25( not f(x) = x3 − 7x2 + 9x − 5) to get the sign diagram in Figure 3.3.3.
