Best ResponseYou've already chosen the best response.0look for example at 5x^2+9x2 look for 2 numbers whose product is 2*5=10 and whose sum is 9

Best ResponseYou've already chosen the best response.0((x+2)(5x1))/(x+10)(x+2)* ((x+7)(x+10)/3(5x1) the way u apporach them is what numbers multiply to give lets say 70... well 7 and 10 . do they add to form the 17x yes cause 10 +7+17.

Best ResponseYou've already chosen the best response.1\[\frac{ (x+2)(5x+1) }{ (x+10)(x+2)} * \frac{ (x+10)(x+7) }{ 3(5x+1) }\] (5x+1) cancels (x + 10) cancels \[\frac{ x+2 }{ x+2 } * \frac{ x+7 }{ 3} = 1 * \frac{ x + 7 }{ 3 } = \frac{ x+7 }{ 3 }\] This, I cannot factor anymore.
