Factorization: Factorizing Trinomials

This lesson covers factorizing quadratic trinomials in two parts. The first part deals with trinomials where A is 1 or -1, while the second part addresses cases where A is not 1 or -1. The lesson provides step-by-step instructions for factorization, including finding two numbers whose product is C and sum is B. Advanced techniques for more complex trinomials are also discussed. The lesson concludes with a summary and encourages applying the learned rules to solve more examples.

What is the first step in factorizing a quadratic trinomial where A is positive or -1?

• Find the product of the means.

• Factorize the first term in parenthesis.

• Calculate the sum of the last two terms.

• Arrange the terms in descending order.

In the first part of factorizing quadratic trinomials, what should the product of the last two numbers equal?

• The constant term C.

• The sum of the first term.

• The middle term B.

• The coefficient of A.

When factorizing a quadratic trinomial where A is not equal to 1, what is the first step?

• Arrange the expression in descending order of X.

• Calculate the product of extremes.

• Factorize the first term AX and X.

• Find the highest common factor.

In the second part of factorizing quadratic trinomials, what should the sum of the product of means and extremes equal?

• The middle term.

• The sum of all terms.

• The first term.

• The last term.

What is the final step after understanding both parts of factorizing quadratic trinomials?

• Write down the steps.

• Rewatch the video.

• Solve more examples.

• Memorize the rules.
