Best ResponseYou've already chosen the best response.0@ganeshie8 certainly I don't understand how I should start? Will you guys be willing to show me the first step? Thee are certain expressions that just dont ring a bell on me, it's not that I cant factor, just some specific ones

Best ResponseYou've already chosen the best response.0\[2x ^{2}+x3=2x ^{2}+3x2x3\] (2*3=6,32=1) \[=x \left( 2x+3 \right)1\left( 2x+3 \right)=\left( 2x+3 \right)\left( x1 \right)\]

Best ResponseYou've already chosen the best response.0So we dont take into considaration b ? We just add and multiply a and c?

Best ResponseYou've already chosen the best response.1\(2x^2 + x  3\) you need to rewrite x as 3x2x

Best ResponseYou've already chosen the best response.1we did consider b, the numbers we pick must multiply to ac, and addup to b

Best ResponseYou've already chosen the best response.0"3 * 2 = 6" "3 + 2 = 1" Where is b ?

Best ResponseYou've already chosen the best response.1we picked 3 and 2, cuz they multiply to ac, and addup to b

Best ResponseYou've already chosen the best response.0yea I know it's 1, I just dont know what do it with it :D

Best ResponseYou've already chosen the best response.1so when you're asking where is b, you knw now that its there, and it is 1 :)

Best ResponseYou've already chosen the best response.0from my understanding we take a*c = whatever it gives then a+c = whatever it gives

ganeshie8

Best ResponseYou've already chosen the best response.1we take a*c, tell whats a*c, in our current example ?

ganeshie8

Best ResponseYou've already chosen the best response.1so we take that 6, and find its factors. that addup to b

Best ResponseYou've already chosen the best response.1when u add both the numbers, you must get b

ganeshie8

Best ResponseYou've already chosen the best response.1we picked 3 and 2, add them and see if u get b or not

Best ResponseYou've already chosen the best response.1if p, q are the two numbers, you should pick them in a way such that : pq = ac p+q = b

Best ResponseYou've already chosen the best response.0Ok so, we have a*c = 6 ab = 1 but how do I proceed with this information in hand?

Best ResponseYou've already chosen the best response.1heres the full solution, go through \(2x^2 + x  3\) \(2x^2 + 3x  2x  3\) \(x(2x + 3)  1(2x + 3)\) \((2x + 3)(x  1)\)
