Q. The polynomial p(x)=x37x6 p(x)=x^{3}-7 x-6 has a known factor of (x+1) (x+1) .\newlineRewrite p(x) p(x) as a product of linear factors.\newlinep(x)= p(x)=
  1. Factor Finding Method: Since we know that (x+1)(x + 1) is a factor of p(x)p(x), we can perform polynomial division or use synthetic division to divide p(x)p(x) by (x+1)(x + 1) to find the other factors.
  2. Synthetic Division Setup: Let's use synthetic division to divide p(x)p(x) by (x+1)(x + 1). We set up the synthetic division with 1-1 (the zero of the factor x+1x + 1) and the coefficients of p(x)p(x): 11 (for x3x^3), 00 (for x2x^2, since there is no x2x^2 term), (x+1)(x + 1)00 (for (x+1)(x + 1)11), and (x+1)(x + 1)22 (constant term).
  3. Performing Synthetic Division: Performing synthetic division, we bring down the leading 11, multiply it by 1-1 to get 1-1, add this to the next coefficient (0)(0) to get 1-1, multiply 1-1 by 1-1 to get 11, add this to 7-7 to get 6-6, multiply 6-6 by 1-1 to get 1-122, and add this to 6-6 to get 1-144. The result of the synthetic division is the coefficients of the quotient polynomial: 11 (for 1-166), 1-1 (for 1-188), and 6-6 (for the constant term).
  4. Quotient Polynomial: The quotient polynomial is x2x6x^2 - x - 6. We can factor this quadratic polynomial to find the other linear factors of p(x)p(x).
  5. Factoring Quadratic Polynomial: Factoring x2x6x^2 - x - 6, we look for two numbers that multiply to 6-6 and add to 1-1. These numbers are 3-3 and 22. Therefore, x2x6x^2 - x - 6 factors into (x3)(x+2)(x - 3)(x + 2).
  6. Final Solution: Now we can write p(x)p(x) as a product of its linear factors: p(x)=(x+1)(x3)(x+2)p(x) = (x + 1)(x - 3)(x + 2).
