I am trying to answer some problems regarding simple equations and rational numbers, and I have an algebra book, but it shows me nothing. It does explain however that common factors are not equal to zero... Though that doesn't teach me much. Could someone please help me?

The equation is this:

$$ 49x^2 - 98x + 40 = 0 $$

Thank you.

    In your comment to Patrick's answer you mentioned that you've found a factorization of the left-hand side. Why didn't you mention that in your question?2011-11-20

    If you have found a factorization of the left side, then it is not clear what your question is. What do you need help with?2011-11-20
