Homework Statement
I did some refresher exercises in khan academy. I tried to wrap my head around the factoring problems, but it did not go well...
I did not understand the khan academy tips and hints. (about factoring)
one particular difficult polynomial was thus: factorize the polynomial.
##6x^2 +11x -35##
according to khan academy this can yet be further factorized (in some manner)
I looked at the hints section of the problem, but I could not understand the method by which the factorization was found. (it was not apparently the "guessing inside the parenthesis" method)
Homework Equations
3. The Attempt at a Solution [/B]
looking at the x-term
It can be seen that 11 is a prime number therefore factor cannot be found for 11, unless it is 1?
greatest common factor does not apparently exist because of 11 is prime, and it's not factor of 6 and neither of -35
I was taught many years ago in high school to use the guessing-method of trying to find the factor...
But I was not very good at this technique. Is there a better way to help in factoring?
I'm sorry I cannot be more productive at this problem... But I was quite stuck on this problem.
