1. The problem statement, all variables and given/known data Find the slope(s) of the tangent at x = 1 for 2y^2 - xy -x^2 = 0 2. Relevant equations 3. The attempt at a solution Ive figured the derivative to be 2x+4/4y+x But I dont know how to make this equation work to find a y value so I can find the slope. I tried singling out a y value and got y = 1 but im not sure if thats the correct way to go about doing this question. Thank You for your help!
