Find Common Factors: Look for common factors in each term of the polynomial 4c7−2c5+c2−5. Upon inspection, there is no common factor for all terms. However, we can group terms to see if there are common factors within the groups.
Group Terms: Group the terms to find common factors within the groups.We can group the first two terms and the last two terms: 4c7−2c5 + c2−5.Now, let's factor out the common factors within each group.
Factor First Group: Factor out the greatest common factor from the first group 4c7−2c5. The greatest common factor is 2c5, so we get 2c5(2c2−1).
Factor Second Group: Factor out the greatest common factor from the second group c2−5. There is no common factor other than 1, so this group remains as it is: (c2−5).
Write Partially Factored Form: Write down the partially factored form of the polynomial.We have factored the polynomial as far as common factors within groups allow: 2c5(2c2−1)+(c2−5).
Look for Patterns: Look for patterns or special products that might help further factor the polynomial. There are no obvious patterns like difference of squares, perfect square trinomials, or sum/difference of cubes that apply to the terms we have. The polynomial does not seem to factor further using standard algebraic techniques.
Conclude Factoring: Conclude that the polynomial is factored as much as possible with the given techniques. The polynomial 4c7−2c5+c2−5 is factored to 2c5(2c2−1)+(c2−5), and no further factoring is possible.
