Factor the polynomial {eq}3x^2+23x+30 {/eq} by grouping. Notice that this polynomial is a quadratic trinomial. In this case, the middle term can be broken up into a sum. To find the numbers of this sum, we need to multiply the coefficient of the leading term by the last term,...
Using factorization by groupings, factor out the polynomial 6x2+ 14x + 9x + 21. Solution Step-by-step ProcessExplanation 6x2+ 14x + 9x + 21Observe the given polynomial and see if each term has a common factor. Since not all terms have a common factor, we can use factorization by gr...
To factor a trinomial of the formax2+bx+cax2+bx+cby grouping, we find two numbers with a product ofacacand a sum ofbb. We use these numbers to divide thexxterm into the sum of two terms and factor each portion of the expression separately then factor out the GCF of the entire exp...

There is one special case for factoring that you may or may not need, depending upon how your book is structured and how your instructor intends to teach factoring quadratics. I call it "factoring in pairs", but your book may refer to it as "factoring by grouping". By whatever name, ...
Factoring by grouping requires the original polynomial to have a specific pattern that not all four term polynomials will have. If you do the factorization in step three and the two groups don't have a common factor then you need to go back to square one and try a different approach. ...
Factoring by Grouping: Group terms to find common factors within each group. Removing the Impostor: Adjust the trinomial to facilitate easier factoring by eliminating conflicting terms. 3. Factoring Perfect Square Trinomials Description: Recognize and factor trinomials that are perfect squares, i.e., ...
There are a number of methods we can use to factor polynomials: factoring out the greatest common factor (GCF), factoring by grouping, factoring the difference of two squares, and factoring the sum or difference of two cubes. The first step in factoring is always to factor out the if any...

Always check your work by multiplying out the factors using the FOIL method. The factors should always multiply back to the original quadratic equation. References West Texas A & M University Virtual Math Lab: The GCF and Factoring by Grouping ...
