Roots Solution. Determine all real numbers A such that Ax3 + (2 – A)x2 – x – 1 has three real roots r1, r2 and r3, two of which have the same value, that is, r1= r2, r2 = r3 or r1= r3. Create, for each such A, (A: r1, r2, r3), where A is a real number and r1, r2 and r3 are the associated real roots, two of …

Otherwise, the equation has two complex roots that are complex conjugates of one another. (We are assuming that a, b and c are real values.) In general with polynomial equations with all real roots, complex roots come in pairs that are complex conjugates of one another. (Note: the complex conjugate of a + bi is a – bi, where a and b are real.)

The number of negative real roots of p(x) is equal to the number of variations of sign in p((x) or is less than that number by an even integer. Example 2: Discuss the number of positive and negative roots of the polynomial: Solution: We note that three are 3 variations of sign I f(x), hence the function has 3 or 1 positive real roots.
