Lol i know how it works, we were taught this method afterthe cross multiplication method where you draw a large plus sign then put numbers in side like X^2 + 6 on the bottom left space then the 5x at the bottom right space. then extend upwards.. it should look like....
X + 3 l 3X
X + 2 l 2X
__________
X^2 + 6l 5X
X multiply by X = X^2 and 3 x 2 = 6 then 3X + 2X = 5X.... then the equation transforms into. (X + 3)(X + 2) = 0 then either X + 3 = 0 or X + 2 = 0
Thus X = -2 or -3...
Assuming this is in fact a quadratic equation (as that is the only way I have found to complete this sum) I do believe this is the answer according to my calculations.
x2+6x+9=x+3
x2+5x+6=0
(x+2)(x+3)
x+2=0 x+3=0
x=-2 x=-3
why am i getting all the red thumbs when my answer is right? i know the other possibility would be -3, but still i got part of the answer right, and this dude who says x=1 and x=-6 get's no red thumbs? Fack you gayjunk, 9gag legin army will destroy you, we well hack you're notepads and take down this website
because you suck at math if you put -2 in the original equation you would see that it is 4-12-9=1 shortened that would be -17 =1 therefore you're an idiot and I sentence this red thumb upon you.
ax^2+bx+c=dx+e
ax^2+(b-d)x+(c-e)=0
x=[-(b-d)(+or-)sqrt(b^2-2bd+d^2-4a(c-e))]/2a
plug in our numbers for our specific solution and get
x=[-(6-1)(+or-)sqrt(36-12+1-24)]2
x=[-5(+or-)sqrt(1)]/2
x=-6/2 or -4/2
x=-2 or x=-3
nope, he's right.
