r u asking for the answer?
The steps and the answer
oh well there is only one step actually so ill just say the answer 10y squared - 20y
i couldnt figure out how to type a small 2
Wait so its 20y?? Where did the x go...?
and @jim_thompson5910 she wanted the answer
multiply the outer `5y` by each of the inner terms ( `2x` and `-4`) |dw:1442547636835:dw|
Jim always shows me the steps and 10xy-20y??
yeah it's 10xy-20y |dw:1442547701927: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 ??
(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
whats the GCF of 2,6, and 36
6 isn't a factor of 2
Omg i meant 2 im so sorry
so we can factor out 2 to get 2*(....) what goes in the blank?
now factor x^2 - 3x - 18
Would it be x-15?? Idk what to do
so overall, the entire thing factors to 2(x-6)(x+3)
Is the answer 2(x-6)(x+3)? If so thank you for all of your help
yeah it is
