Best ResponseYou've already chosen the best response.0So, what's the question? Are we supposed to factor it out?

Best ResponseYou've already chosen the best response.2first take x out of the quadratic function

Best ResponseYou've already chosen the best response.0But one is negative and one isn't..

Best ResponseYou've already chosen the best response.2oh sorry you can simplify first (x^2+5x−14x^2 = 5x  13x^2 = x(5  13x)

Best ResponseYou've already chosen the best response.2there are no common factors here are you sure you have the question right?

Best ResponseYou've already chosen the best response.0The 14 isn't supposed to have \(x^2\)

Best ResponseYou've already chosen the best response.2i suspect thet the quadratic is x^2+5x−14

Best ResponseYou've already chosen the best response.2to factor x^2+5x−14 you need to find 2 numbers whose product is 14 and whose sum is +5

Best ResponseYou've already chosen the best response.2can you tell me what those 2 numbers sre?

welshfella

Best ResponseYou've already chosen the best response.2think of the factors of 14

inowalst

Best ResponseYou've already chosen the best response.0Their product has to be 14 but the sum has to be 5?

Best ResponseYou've already chosen the best response.0Hm.. I don't really know, but I know for the 14..

Best ResponseYou've already chosen the best response.214 = 7 * 2 or 14 = 2 * 7

Best ResponseYou've already chosen the best response.2which 2 factors add up to +5?

welshfella

Best ResponseYou've already chosen the best response.2right on so the factors of (x^2+5x−14) are ( x  7)(x + 2)

Best ResponseYou've already chosen the best response.2if you expand this function you'll see it works out to x^2 + 5x  14

welshfella

Best ResponseYou've already chosen the best response.2* oops my bad its (x + 7)(x  2)

Best ResponseYou've already chosen the best response.0Yes. Thank you so much.

Best ResponseYou've already chosen the best response.2Now you need to factor x^2  49

Best ResponseYou've already chosen the best response.0(x7)(x+7) ? I don't know..

welshfella

Best ResponseYou've already chosen the best response.249  x^2 = (7  x)(7 + x) so can you see the common factor?

Best ResponseYou've already chosen the best response.0Oh, okay. Thanks a bunch.
