simple question how to factorize x2-x-6

[sly pilot]

ok

@bold gyro what pair of numbers that summer together equal to 1 and multiplied together equal to -6

because x = 1x

dang it issac

[bold gyro]

Ok

[sly pilot]

ok

as i mentioned above, what pair of number?

[bold gyro]

Why is it -3 +2

I don't understand

[sly pilot]

-3 + 2 = -1

almost correct

[bold gyro]

3 -2?

[sly pilot]

yes its -2 + 3

now

split the x into -2x + 3x, which mean that summed together it equal x, and multiplied together equals to -6

now the equation looks like this

[bold gyro]

So is question 4 wrong?

[sly pilot]

$x^2-2x+3x-6$

[sly pilot]

it is not wrong

[sly pilot]

the equation after expanding looks like this

[bold gyro]

But I wrote -3 and +2

[sly pilot]

then write -2 + 3

it is wrong

well wait

lemme calculate

[sly pilot]

-3x + 2x = -1x you know

[bold gyro]

Yes

[sly pilot]

you need to split it correctly

wait

uh

@bold gyro it works both way

so now

according to your split

the equation looks like this

$x^2-3x+2x-6$

[bold gyro]

Ok

[sly pilot]

@bold gyro now it look like this

now group the first 2 number and last 2 number into a pair

it will look like this

$x(x-3)+(2x-6)$

i will do an example for the first pair @bold gyro

[bold gyro]

But the answer says I'm right

[wary thicket]

[sly pilot]

we are solving it, lets get into the answer later

[bold gyro]

Ok

[sly pilot]

can you solve the second pair @bold gyro

what does 2x and 6 have in common

[bold gyro]

2

[sly pilot]

yes

now it look like this

$x(x-3)+2(x-3)$

[wary thicket]

PooPoo, not CEO of comedy

[sly pilot]

you can see that both side have (x-3)

[bold gyro]

Ok

[sly pilot]

so

group them

then it look like

$(x+2)(x-3)$

[bold gyro]

Oh

[sly pilot]

there is your finished product

[bold gyro]

Thanks
