2x^2+x3 factored would be (2x+3)(x1)

@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

i understand, let me guide u factor this

we need to pick two numbers whose product equals \(ac\), and sum equals \(b\)
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
can you pick two numbers whose product equals 6, and sum equals 1 ?

\[2x ^{2}+x3=2x ^{2}+3x2x3\] (2*3=6,32=1) \[=x \left( 2x+3 \right)1\left( 2x+3 \right)=\left( 2x+3 \right)\left( x1 \right)\]

I dont think I can :(

ganeshie8Best ResponseYou've already chosen the best response.1
tell me what are the factors of 6
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
3 and 2 are our numbers !
 11 months ago

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

ganeshie8Best ResponseYou've already chosen the best response.1
\(2x^2 + x  3\) you need to rewrite x as 3x2x
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
we did consider b, the numbers we pick must multiply to ac, and addup to b
 11 months ago

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

ganeshie8Best ResponseYou've already chosen the best response.1
we picked 3 and 2, cuz they multiply to ac, and addup to b
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
look at the given expression, b = 1

ChristosBest ResponseYou've already chosen the best response.0
hm the second expression ye
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
\(2x^2 + x  3\) can be written as : \(2x^2 + 1x  3\)

ganeshie8Best ResponseYou've already chosen the best response.1
compare it wid ax^2 + bx + c, and tell me whats b ?
 11 months ago

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

ganeshie8Best ResponseYou've already chosen the best response.1
so when you're asking where is b, you knw now that its there, and it is 1 :)
 11 months ago

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

ganeshie8Best ResponseYou've already chosen the best response.1
we take a*c, tell whats a*c, in our current example ?
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
so we take that 6, and find its factors. that addup to b

when you say "add up" what do you mean exactly?
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
when u add both the numbers, you must get b
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
we picked 3 and 2, add them and see if u get b or not
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
if p, q are the two numbers, you should pick them in a way such that : pq = ac p+q = b
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
great :) you do few more problems u wil see more clearly
 11 months ago

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

ganeshie8Best ResponseYou've already chosen the best response.1
heres the full solution, go through \(2x^2 + x  3\) \(2x^2 + 3x  2x  3\) \(x(2x + 3)  1(2x + 3)\) \((2x + 3)(x  1)\)

/facepalm I am such a dummy some times, I can see it clearly now, thanks again
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
its, pq = ac p+q = b
 11 months ago

ganeshie8Best ResponseYou've already chosen the best response.1
cool all geniuses have few dummy corners ;p
