New way to find vertex ok if I have y = x^2+6x+8 so 9+y = (x^2+6x+9) + 8 we subtract 8 so we have 9-8+y = (x+3)^2  we have (1+y) = (x+3)^2 right and 1+y=0 y is equal to -1 and x is x+3= 0 x is -3 :)

New formula 3x^2-2x-8 = 3x-8 = -24 right factors of -24 is -6x4 or 6x-4 right so -6+4 = -2 right We exchange -2x to -6x+4x (3x^2-6x)+(4x-8)= 3x(x-2)+4(x-2) rightanswer is (3x+4)(x-2)
