\[x ^{2}-4x-12=0 ???\]

Answer 3

in school do they teach you quadratic formula or factor method?

Answer 4

x^2+2x-6x-12
Factor !!

Answer 5

quadratic formula

Answer 6

supraron you lost me

Answer 7

Start by making the equation equal to 0, do this by -4x both sides of the equation.

x^2-4x-12=0

Now in order to factorise you are looking for two numbers which add to give -4 and multiply to give -12.

In this cause the two factors are

x=2
x=-6

Thus:

(x+2)(x-6)=0

For this equation to be true

x=-2
x=6

Answer 8

do you know what is the quadratic formula?

Answer 9

Oh then plug in the numbers \[-b \pm \sqrt{b^2-4ac} all \over 2a\]
