How would we solve this?

2. Use the function f (x, y) = xy+ 2xey to answer the questions below. A) Find the equation of the tangent plane at the point (1, 0). SHOW WORK. B) Find differential of f in moving from the point (1, 0) to the point (0.8,02). SHOW WORK. C) Use the linear approximation to this function at the point (1, 0) to estimate the value of f (0.8, 0.2). SHOW WORK. (15)
