      Help teh Ooflendoodle

      I'll just post questions I have that I'm stuck on, I would prefer explanations so I can understand this myself and not have to ask in the future. Thanks

      So I think this one is impossible but I'm probably wrong, how would you factor xsquared-7x-10. If you could give me the explanation and answer that would be great.

      (X-5)(X-2)

      X2-7X-10 OK, so you would have 2 X's in each parenthesis like this: (X-_)times(X-_)
      It's minus for both, because there are 2 minuses. The rest is just trial and error.

      Oh! sorry. It's one positive and one negative then.
      I haven't factored in years. My bad.

      hmm
      that also doesn't work because I would have a positive 5 or 2 which wouldn't get me to negative 7 this has to be a typo.

      That's true. Weird. 10 only factors into 1 and 10 or 5 and 2. it would have to be Xsquared-7+10... Bummer.

      If you have a second degree expression you have to factor, one way of always getting the right answer is to set it equal to 0 and solve the resulting equation.
      x2 - 7x - 10 = 0
      Gives the solutions x = (1/2)(7 - sqrt(89)) and x = (1/2)(7 - sqrt(89))
      Thus the factorized form is: (x - (1/2)(7 - sqrt(89))) (x - (1/2)(7 - sqrt(89)))

      (That's (x-s1)(x-s2), with s1 and s2 being the two solutions)
