A) 4 B) none C) 12 D) 3 The greatest common factor, or GCF, of an algebraic expression, is the greatest monomial that can divide evenly into allterms of the expression. For example, the GCF of 30x2y + 20y is 10y. What is the GCF of this binomial? 2x2 - 12 Hint: Sometimes the GCF will have a coefficient AND a variable! What is the GCF of this binomial? 4x2 - 16x What is the GCF of this trinomial? 15x2y - 5xy - 10y What is the GCF of this trinomial? 8x2 - 4x - 20 What is the GCF of this trinomial? 15x3 - 9x2 - 3x What goes outside the parenthesis when factoring 15x – 25? 15x - 25 = GCF (3x - 5 ) Factor 2x2 + 36x by factoring out the GCF. 2x2 + 36x = ( x + 18 ) = Fill in either a '+' or a '-'. ( x x2 + 10x + 16 8) ( x 2) = Fill in either a '+' or a '-'. ( x x2 + 8x - 20 10) ( x 2) = Fill in either a '+' or a '-'. ( x x2 - 4x - 12 6) ( x 2) = Fill in either a '+' or a '-'. ( x x2 - 9x + 20 4) ( x 5) = ( x + )(x - ) Fill in the blanks x2 + 4x - 5 = ( x + )(x - ) Fill in the blanks x2 + 7x - 18 = ( x - )(x + ) Fill in the blanks x2 + 3x - 10 = Fill in the blanks, with the smallest number in the first factor ( x - )(x + ) x2 + 7x + 10 = Fill in the blanks, with the smallest number in the first factor ( x - )(x + ) x2 - x - 12 = Fill in the blanks, with the smallest number in the first factor ( x - )(x + ) x2 + 2x - 15 |
