Best ResponseYou've already chosen the best response.0oh.. ok well my original problem i needed to solve was 42x^2+141x=21 and i thought i was on the right track... maybe not?

Best ResponseYou've already chosen the best response.0The only thing that will make 14x^2 is (7x )*(2x ). Now, the only factors that give the 7 is 7 and 1. With this knowledge you get (7x1)*(2x7)

Best ResponseYou've already chosen the best response.0Wrong; is it possible that taking out 3 was all you were meant to do? Because it can;t go any further.

Best ResponseYou've already chosen the best response.0hmm.. maybe but the example i followed came up with two terms which then i put to the zero factor property... but maybe this is as far as this one goes.

Best ResponseYou've already chosen the best response.0I put it through the answer check and it said that 14x^247x+7 was wrong

Best ResponseYou've already chosen the best response.0it said the methods to solving were either the quadratic formula or by completing the square.

Best ResponseYou've already chosen the best response.0\[\sqrt{47^24 \times 7 \times 14} \notin \mathbb{Z^+}\] therefore it won't factorise Completing the square doesn't look too friendly on this one; just go with the formula

Best ResponseYou've already chosen the best response.0\[x = \frac{47 \pm \sqrt{1817}}{28}\] ...dunoo how that will go in your 'answer check'

Best ResponseYou've already chosen the best response.0just an update... apparently 14x^247x+7=) factors into (7x+1)(2x7)... which in turn would make the real number solutions: 1/7 and 7/2
