Math Problem Statement

8(x-a)(x-b)(x-c) where a,b and c were constants and (r,s) is a solution.

Solution

Given the expression 8(xa)(xb)(xc)8(x-a)(x-b)(x-c), where aa, bb, and cc are constants, and (r,s)(r, s) is a solution, we need to clarify whether rr and ss are roots of the equation formed by setting this expression equal to zero or if they are specific values for xx and the corresponding value of the expression.

Case 1: rr and ss as roots

If (r,s)(r, s) represents roots of the polynomial equation 8(xa)(xb)(xc)=08(x-a)(x-b)(x-c) = 0, then rr, ss, and another value (since it's a cubic polynomial) are the roots of the equation. So,

r=a,s=borr=a,s=corr=b,s=cr = a, \quad s = b \quad \text{or} \quad r = a, \quad s = c \quad \text{or} \quad r = b, \quad s = c

This would mean that rr, ss, and the third constant (which is aa, bb, or cc depending on the pairs chosen) satisfy the equation individually.

Case 2: (r,s)(r, s) as an xx-value and corresponding polynomial value

If rr is the value of xx, and ss is the value of the polynomial at x=rx = r, then:

s=8(ra)(rb)(rc)s = 8(r-a)(r-b)(r-c)

In this case, rr is not necessarily equal to aa, bb, or cc; it's just the input for xx in the polynomial, and ss is the corresponding output.

Would you like to explore one of these scenarios in detail or discuss a different interpretation?


Here are 5 related questions that expand on this information:

  1. If rr and ss are roots, what would the third root of the polynomial be?
  2. How would the expression change if aa, bb, and cc are complex numbers?
  3. What would the polynomial look like if we expanded 8(xa)(xb)(xc)8(x-a)(x-b)(x-c)?
  4. How can we find the vertex of the curve defined by 8(xa)(xb)(xc)=08(x-a)(x-b)(x-c) = 0?
  5. What is the significance of the constant 8 in the expression?

Tip: When analyzing polynomials, carefully consider whether you are dealing with roots or specific function values, as this affects the interpretation and solution method.
