Question: tangent and normal function

The original function is 6x^2+5x-4/2x^2-7x-4. The equation of the line which is tangent to the curve at the point (0,1) is -12/35x - 1/35. Is this correct? I used the command Tangent(f(x),x=-3). The equation of the line which is normal to the curve at the point (-3,1). is 35/12 + 39/4 . Is this correct?
