Sample answers: Students will have different trinomials since they are randomly generated. To factor a trinomial: Check to see if the terms are IN ORDER (Ascending or Descending) Check to see if its an “Easy” or “Hard” Trinomial a. As factoring is multiplication backwards we will start with a multipication problem and look at how we can reverse the process. Factoring by grouping (type IV) can help us: Factor 15x2 + 13x + 2 METHOD 1) Factor out GCF if … Be aware of opposites: Ex.

FACTORING TRINOMIALS OF THE FORM x2 + bx + c Factoring with three terms, or trinomials, is the most important technique, especially in further algebra. In this chapter we’ll learn an analogous way to factor polynomials. Step 2 : Decide if the three terms have anything in common, called the greatest common factor or GCF. x��\io�8� �A��D/�lr�`ۻ��v�����(�q�u�G��VQr���r�@�ؒ)=��zE�����||9��������H��M���������j��p4���ӛ��߾�����t^�����8���N����I ��ɬ����/���������{��ܗ���fE"U&�����lM~�l���.�#�����%=�����tVe:��ow�I�����o�;���ݝ �R����iwB/����lϧ>��C�'���IN�=�B�[ΰ�|��o�Ĝ��\�TW;�D�pln)����HN�%�HQ�{��ٞK�?|�T��#۳�4ذB�߱�A*�{ۿ��(��lǘ� endobj Step 5: Multiply leading coefficient 7 with last term 10 to get 7 10 = 70. 2 +10 21 2. One technique is factoring by grouping. If so, factor out the GCF.

Easy trinomial: Always have two sets of parenthesis ( ) ( ) To determine the signs look at the last term: x2 –6x + 9 ( - )( - ) If it … Step 6: List all factors of 70 starting with 1 70 and sequentially work up from 1; see table below. - Finding what was multiplied together (“the factors”) to get an expression (the polynomial ). Factor xy + y + 2x + 2 by grouping. The units covered include: Measurement (measurement, trigonometry), Algebra and Numbers (polynomials, real numbers), Relations and Functions (relations & functions, linear … consider the sign when we add these numbers of different signs). !+2!−3 5) 6 !! To determine the signs of the two factors we are seeking in the table, look at the sign of the last term ‘10’ of the trinomial. You've reached the end of your free preview. 157 Factoring Polynomials Any natural number that is greater than 1 can be factored into a product of prime numbers. For a binomial, check to see if it is any of the following: difference of squares: x 2 – y 2 = ( x + y) ( x – y) difference of cubes: x 3 – y 3 = ( x – y) ( x 2 + xy + y 2) sum of cubes: x 3 + y 3 = ( x + y) ( x 2 – xy + y 2) For a trinomial, check to see whether it is either of the following forms: For all polynomials, first factor out the greatest common factor (GCF). Concept: When factoring polynomials, we are doing reverse multiplication or “un-distributing.” Remember: Factoring is the process of finding the factors that would multiply together to make a certain polynomial. endobj <> Algebra 2 Notes SOL AII.1 Factoring Polynomials Mrs. Grieser Page 5 Method 2: Factor by Grouping Method If you are not a good guesser, it can be hard sometimes to use the guess and check method. 10.4Factoring*Trinomials! 1.
