find the equations of the tangents at the points P and Q The curve ${y = (x -1)(x^2 + 7)}$ meets the x-axis at P and the y-axis at Q.
Find the equations of the tangents P and Q.
I am not looking for the answer but just some hints to get me started.
I am not sure how to being.

HINT:
Find derivatives of y at x=0 and x = 1, and y values there. For each point find 
$$ \frac{y-y_1}{x-x_1} = derivative $$
