Q. The polynomial p(x)=3x35x24x+4 p(x)=3 x^{3}-5 x^{2}-4 x+4 has a known factor of (x2) (x-2) .\newlineRewrite p(x) p(x) as a product of linear factors.\newlinep(x)= p(x)=
  1. Perform polynomial long division or synthetic division: Since we know that (x2)(x-2) is a factor of p(x)p(x), we can perform polynomial long division or synthetic division to divide p(x)p(x) by (x2)(x-2).
  2. Set up synthetic division with known factor: Set up the synthetic division with the root of the known factor, which is 22, and the coefficients of p(x)p(x): 33, 5-5, 4-4, and 44.
  3. Perform synthetic division: Perform the synthetic division. Bring down the leading coefficient 33 to the bottom row.
  4. Multiply root by value and write result: Multiply the root 22 by the value just brought down 33 and write the result 66 under the next coefficient 5 -5.
  5. Add values and write result: Add the values in the second column (5+6=1-5 + 6 = 1) and write the result (11) in the bottom row.
  6. Repeat the process: Repeat the process: multiply the root (2)(2) by the new value in the bottom row (1)(1) to get 22, and write this under the next coefficient (4)(-4).
  7. Add values and write result: Add the values in the third column (4+2=2-4 + 2 = -2) and write the result (2-2) in the bottom row.
  8. Repeat the process one last time: Repeat the process one last time: multiply the root 22 by the new value in the bottom row 2-2 to get 4-4, and write this under the last coefficient 44.
  9. Confirm (x2)(x-2) as a factor: Add the values in the last column (4+(4)=0)(4 + (-4) = 0) and write the result (0)(0) in the bottom row. Since the remainder is 00, this confirms that (x2)(x-2) is indeed a factor of p(x)p(x).
  10. Coefficients of quotient polynomial: The result of the synthetic division gives us the coefficients of the quotient polynomial, which are 33, 11, and 2-2. This means p(x)p(x) can be written as (x2)(3x2+x2)(x-2)(3x^2 + x - 2).
  11. Factor the quadratic polynomial: Now we need to factor the quadratic polynomial 3x2+x23x^2 + x - 2. We look for two numbers that multiply to 6-6 (3×23 \times -2) and add to 11 (the coefficient of xx). These numbers are 22 and 3-3.
  12. Write quadratic polynomial as a product: Write the quadratic polynomial as a product of two binomials using the numbers found in the previous step: 3x2+x2=(3x2)(x+1)3x^2 + x - 2 = (3x - 2)(x + 1).
  13. Combine factors to express p(x)p(x): Combine the factors to express p(x)p(x) as a product of linear factors: p(x)=(x2)(3x2)(x+1)p(x) = (x - 2)(3x - 2)(x + 1).
