I really need help. I've checked everywhere and it says cannot be factored. I will give brainliest to whoever can help me and give the correct answer. PLEASE HURRY!

B) -5, 5, -7, 7           

Step-by-step explanation:

3x² - bx + 2

factor:

(3x - 2 )(x - 1) = 3x² - (5)x + 2      so 5 does work

(3x - 1 )(x - 2) = 3x² - (7)x + 2      so 7 does work

(3x + 2 )(x + 1) = 3x² + 5x +2    =    3x² - (-5)x + 2      so -5 does work

(3x + 1 )(x + 2) = 3x² + 7x + 2   =    3x² - (-7)x + 2      so -7 does work

each side has a different length.  

step-by-step explanation:

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can
