Im massively confused what would I do if I had " x^2 - 3/4x + 1/8 = 0 "

@scoupafi <--to: Yep, your answer is correct, according to the problem you have presented, which needs to be further simplifed first, before factoring, by adding (-5x) + (-2x), which will = -7x. So, you did that right. Now factor it, and your correct answer will be: (x - 5)(x - 2)

@RSwanson1972 I have tried what you did out of curiosity and my results are these:
x(square)-5x-2x+10 = x(square)-7x+10.
Not what I want right/?

Your last example is WRONG!!! It is a PRIME trinomial and can not be factored. In this case you must have a negative sign in both parentheses; however, if you look at your last example: + 2 times -5 = - 10 wich is incorrect. When multiplying 2 and 5, your answer must equal a +10 and not a -10. Check your work and see for your-self throught the FOIL method. =)P

He loused up the second problem because the answer as he gives it would come out x^2-3x-10 not x^2-3x+10 like he had planned. Maybe that's why the video is cut short.

it really helped me :)

he made a mistake, that +10 should be a negative. because +2 (-5)=-10
