Factoring when it at 1 Part 1 This is part 1 of a two part assignment where you will practice factoring quadratic expressions when the coefficient of x: is not equal to 1. Rewrite each of the following quadratic expressions into a form where you can perform factor by grouping by splitting the middle term up into two parts. The numbers can he found using mental math by ensuring they multiply to or and add up to I}. Ex: 312 13x II} in this case,o = 3J1 = 13,ond c = 1i]. Thus or: ={3][1[l']= 3i]. You need two numbers which multiply to 3 and add up to 13. 15 and 2 will accomplish that. So. you will rewrite the problem into 312 15:: + 2x 1i]. 1. 512 13:: I5 2.6x2111+3 3.112 +3x+8 4. 12::2 + 231' s 5. 912 18x+
