3x2 + 2x + 3 + x2 + x + 1 = 4x 2+ 3x + 4
It is: (x+4)(x-2) when factored
X2 + 2X - 14 = 6X2 + 2X - 8 = 0what two products of - 8 = 2 ?(X +4)(X - 2)=========X = - 4X = 2
x2+2x-4 = 0 x = (-2 plus/minus sqrt (4-(4x1x-4)) / 2 x = (-2 plus/minus sqrt 20)/2 x = (-2 - sqrt 20)/2 or (-2 + sqrt 20)/2 x = -3.236 or 1.236
X3 + 8= (x+2)(x2-2x+4)
