Outline Essential Question Factoring using X method Examples

Essential Question How do I factor trinomials using the X method?

Factoring Using the X method To factor a trinomial means to write it as the product of two binomials. Factor x2 + 6x +8

Factoring Using the X method x2 + 6x +8 What two numbers multiply to give you 8, but add to give you 6? 8 2 4 6

Factoring Using the X method x2 + 6x +8 (x+__)(x+__) (x+2)(x+4) 8 2 4 6

Examples x2 - x -42 What two numbers multiply to give you -42, but add to give you -1? -42 -7 6 -1

Examples x2 - x -42 (x+__)(x+__) (x-7)(x+6) -42 -7 6 -1

Examples x2 - 16x +64 (x+__)(x+__) (x-8)(x-8) 64 -8 -8 -16

Examples x2 - 3x +2 (x+__)(x+__) (x-2)(x-1) 2 -2 -1 -3
