  • jim_thompson5910
multiply the outer `5y` by each of the inner terms ( `2x` and `-4`) |dw:1442547636835:dw|

I understand that now, thank you for explain in detail :) Also, could you let me know if i did this correct. What is the product of the following after multiplied by FOIL? (x+3)(x-7) = x^2-4x-21 ??
jim_thompson5910
  • jim_thompson5910
(x+3)(x-7) = x^2-4x-21 is correct. You can use a table like this to verify |dw:1442548028096:dw|

Thank you :) I have one final question that im not to sure how to do. Factor the polynomial first by gcf followed by factorimg the trinomial. Please describe your steps. 2x^2-6x-36
jim_thompson5910
  • jim_thompson5910
whats the GCF of 2,6, and 36
anonymous
  • anonymous
6?
jim_thompson5910
  • jim_thompson5910
6 isn't a factor of 2
anonymous
  • anonymous
Omg i meant 2 im so sorry
jim_thompson5910
  • jim_thompson5910
so we can factor out 2 to get 2*(....) what goes in the blank?
anonymous
  • anonymous
X^2-3x-18
jim_thompson5910
  • jim_thompson5910
yes
jim_thompson5910
  • jim_thompson5910
now factor x^2 - 3x - 18

(X-6)(x+3) ?!?!
jim_thompson5910
  • jim_thompson5910
very good
jim_thompson5910
  • jim_thompson5910
so overall, the entire thing factors to 2(x-6)(x+3)
anonymous
  • anonymous
Is the answer 2(x-6)(x+3)? If so thank you for all of your help
jim_thompson5910
  • jim_thompson5910
yeah it is
