**Do Now:**Write the standard form of an equation of a line passing through (-4,3) with a slope of -2. Write the equation in standard form with integer coefficients y = -1/3x - 4**Do Now:**Worksheet – Match the correct bottle with its graph**Factoring Using the Distributive Property**GCF and Factor by Grouping**Review**1) Factor GCF of 12a2 + 16a • 12a2 = • 16a = Use distributive property**PRIME POLYNOMIALS**A POLYNOMIAL IS PRIME IF IT IS NOT THE PRODUCT OF POLYNOMIALS HAVING INTEGER COEFFICIENTS. TO FACTOR A PLYNOMIAL COMPLETLEY, WRITE IT AS THE PRODUCT OF MONOMIALS PRIME FACTORS WITH AT LEAST TWO TERMS**TELL WHETHER THE POLYNOMIAL IS FACTORED COMPLETELY**2X2 + 8 = 2(X2 + 4) YES, BECAUSE X2 + 4 CANNOT BE FACTORED USING INTEGER COEFFICIENTS 2X2 – 8 = 2(X2 – 4) NO, BECAUSE X2 – 4 CAN BE FACTORED AS (X+2)(X-2)**Using GCF and Grouping to Factor a Polynomial**• First, use parentheses to group terms with common factors. • Next, factor the GCF from each grouping. • Now, Distributive Property…. Group both GCF’s. and bring down one of the other ( ) since they’re both the same.**Using GCF and Grouping to Factor a Polynomial**• First, use parentheses to group terms with common factors. • Next, factor the GCF from each grouping. • Now, Distributive Property….
