try to split the middle term that is the coefficient of x
2 and 2
it means we can't split the middle term as it is not cmg equal to the 2*3=6
try to use another method to solve x that is |dw:1365966175384:dw|
here 2x^2 – 4x – 3 = 0 a=2 b=-4 c=-3

(-4+under root?-4^2-4(2)(-3) / 2(2)
=4
|dw:1365966396906:dw|
now make the factors of 40
Couldn't I just do this: 2x^2-4x-3=0 (x-4)(x+1) x-4=0 x+1=0 x=4 x=-1 ?

1*40=40 2*20=40 4*10=40 5*8=40
this is wrong
undeeroot 40 = underroot 2*2*2*5=4underroot10
what is an under root?
|dw:1365966692514:dw|
