Q. Factor out the greatest common factor. If the greatest common factor is 11, just retype the polynomial.\newline7k22k7k^2 - 2k
  1. Identify GCF of Terms: We need to find the greatest common factor (GCF) of the terms 7k27k^2 and 2k2k. To do this, we look for the highest number that divides both coefficients (77 and 22) and the highest power of kk that is present in both terms.
  2. Coefficients GCF: 11: The coefficients 77 and 22 are both prime numbers and do not have any common factors other than 11. Therefore, the GCF of the coefficients is 11.
  3. Variable Part Analysis: For the variable part, the lowest power of kk present in both terms is k1k^1 (or simply kk), since 7k27k^2 has k2k^2 and 2k2k has k1k^1.
  4. Combine Coefficients and Variable: Combining the GCF of the coefficients and the variable part, we find that the GCF of 7k27k^2 and 2k2k is kk.
  5. Factor Out GCF: Now we factor out the GCF kk from each term:\newline7k2=k×7k7k^2 = k \times 7k\newline2k=k×22k = k \times 2
  6. Write Factored Polynomial: Writing the polynomial with the GCF factored out, we get: 7k22k=k(7k2)7k^2 - 2k = k(7k - 2)
