Question

i dont get this Xsquare+5x+6=0

Answer 1

Factorize the equation first.

So you will get (x+3)(x+2)=0

Answer 2

how did yu do it

Answer 3

(x+3)(x+2)=0
x+3=0 x+2=0
x=-3 x=-2

Answer 4

ok so how you went from X^2+5X+6=0

Answer 5

You need to find to values that when you multiply together, you get 6.

so you have only a few choices:

1 * 6
2 * 3

the problem when you use 1*6 is that you cannot get the 5x to be positive.

Answer 6

Oh sorry. You cannot get the 6 to be positive if you use 1 * 6. Cause your 1 has to become a -1 in order to get the 5x.

Answer 7

o i see

Answer 8

actually, we are going to have a trial and error here, We must find factors of 6 that will give us the sum of 5 and that is 2 and 3.
so will have (x+3)(x+2)=0
you can check if (x+3)(x+2)=0 is equal to X^2+5X+6=0 by FOIL Method
