Factoring a polynomial by grouping

The video tutorial explains how to factor polynomials, focusing on the technique of factoring by grouping. It begins with an introduction to factoring and an overview of various techniques for polynomials with two or three terms. The main focus is on polynomials with four terms, where grouping is the primary method. The tutorial provides a detailed, step-by-step example of factoring a polynomial by grouping, highlighting the importance of identifying common factors and grouping terms effectively. The video concludes with a summary of the process.

What is the first step when factoring a polynomial with more than three terms?

• Step back and consider grouping

• Apply the difference of squares

• Look for a common factor

• Use the AC method

Which method is used for factoring polynomials with four terms?

• Synthetic division

• Difference of cubes

• Grouping

• AC method

When grouping terms in a polynomial, what is the next step after inserting parentheses?

• Divide the terms by a constant

• Factor out the GCF from each group

• Add the terms together

• Multiply the terms

What do you do if the expressions inside the parentheses are identical after grouping?

• Add them together

• Ignore them

• Factor them out as a common expression

• Multiply them by a constant

What is the final result of factoring the polynomial in the example?

• x plus 7 times x squared plus 5

• x squared times x plus 7

• x plus 7

• x squared plus 5
