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

compare it wid \(ax^2 + bx + c\)

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

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
a=2 b=1 c=3

\[2x ^{2}+x3=2x ^{2}+3x2x3\] (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 :(

tell me what are the factors of 6
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
and 1, 2, 3 also
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
so, 3 * 2 = 6
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
3 + 2 = 1
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
3 and 2 are our numbers !
 one year ago

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

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
\(2x^2 + x  3\) you need to rewrite x as 3x2x
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
we did consider b, the numbers we pick must multiply to ac, and addup to b
 one year ago

Christos Group TitleBest ResponseYou've already chosen the best response.0
"3 * 2 = 6" "3 + 2 = 1" Where is b ?
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
we picked 3 and 2, cuz they multiply to ac, and addup to b
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
look at the given expression, b = 1
 one year ago

Christos Group TitleBest ResponseYou've already chosen the best response.0
hm the second expression ye
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
\(2x^2 + x  3\) can be written as : \(2x^2 + 1x  3\)
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
compare it wid ax^2 + bx + c, and tell me whats b ?
 one year ago

Christos Group TitleBest ResponseYou've already chosen the best response.0
yea I know it's 1, I just dont know what do it with it :D
 one year ago

ganeshie8 Group TitleBest 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 :)

Christos Group TitleBest ResponseYou've already chosen the best response.0
from my understanding we take a*c = whatever it gives then a+c = whatever it gives
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
not exactly
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
we take a*c, tell whats a*c, in our current example ?
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
so we take that 6, and find its factors. that addup to b
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
6 = 3*2

when you say "add up" what do you mean exactly?

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
when u add both the numbers, you must get b
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
we picked 3 and 2, add them and see if u get b or not
 one year ago

ganeshie8 Group TitleBest 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
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
thats all
 one year ago

Christos Group TitleBest ResponseYou've already chosen the best response.0
I see now

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
great :) you do few more problems u wil see more clearly

Christos Group TitleBest 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?
 one year ago

ganeshie8 Group TitleBest 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
 one year ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.1
its, pq = ac p+q = b
