So, -b/2a = -8/2(2) = -8/4 = -2 The axis of symmetry is X = -2. Answer by stanbon(57314)   (Show Source): You can put this solution on YOUR website!what is the axis of symmetry of this equation y=2x^2+8x-2 2(x^2+4x+? = y+2+? 2(x^2+4x+4) = y+2+8 2(x+2)^2 = y+10 y = 2(x+2)^2 - 10 ---------------------- Axis of symmetry: x = -2 ========================== Cheers, Stan H.
