I'm not sure about the first sign. If it is the sign for multiplication then your equation would read : X(2)-6X+1. No need to factor, just simplify the inequality which would be: 2X-6X+1
-4X= -1
X=1/4

u cant factor this into -3 and +2 coz its +1 at the end....... so ull find out the discriminant...........
a is co-efficiant of x^2 which is 1
b iis co-efficiant of X which is 6
c is the constant 1
D (discriminant) = b^2 - 4ac
D= 6*6 - 4*1*1
D = 36 - 4
D = 32
now the factors are
[ -b +(D)^1/2 ] \ 2a and [ -b - (D)^1\2 ] \2a
[ 6 + 4 sq rt 2 ] \ 2 and [ 6 - 4 sq rt 2 ] \ 2
so the answer is 3 + 2(sq rt of 2) and 3 - 2(sq rt of 2)
NOW I DESERVE 10 POINTS

I don't think this is factorable. Closest would be (x-6)(x-1/6) but that would give x2-6 and 1/6+ 1.
Hope that helps.

x1=[6+(36-4)^1/2]/2 =3+2(2)^1/2
and x2=[-6-(36-4)^1/2]/2 =-3-2(2)^1/2
