So when x is 2, then y is equal to 10 minus 5/2 times 2, and the 2 in the denominator cancels out with this 2 in the numerator So it simplifies to 10 minus 5, or just 5 So that tells us the point x equals 2, y is equal to 5, is on the line So 2x is equal to 1, 2 right over here And then y is equal to 5Solution for x^2xyy^2=0 equation Simplifying x 2 xy 1y 2 = 0 Reorder the terms xy x 2 1y 2 = 0 Solving xy x 2 1y 2 = 0 Solving for variable 'x' Begin completing the square Move the constant term to the right Add 'y 2 ' to each side of the equation xy x 2 1y 2 y 2 = 0 y 2 Combine like terms 1y 2 y 2 = 0 xy x 2 0 = 0 y 2 xy x 2 = 0 y 2 Remove theExample 2 if x = 10 and y is 4 (10 4) 2 = 10 2 2·10·4 4 2 = 100 80 16 = 36 The opposite is also true 25 a 4a 2 = 5 2 2·2·5 (2a) 2 = (5 2a) 2 Consequences of the above formulas

Times the derivative of the something with respect to x Well, the derivative of x with respect to x is just 1, and the derivative of y with respect to x, that's what we're trying to solve So it's going to be 1 minus dy dx Let me make it a little bit clearer what I just did right over here This right over here is the derivative of x minus yAnd y = −√x (the bottom half of the parabola) Here is the curve y 2 = x It passes through (0, 0) and also (4,2) and (4,−2) Notice that we get 2 values of y for each value of xSOLUTION 13 Begin with x 2 xy y 2 = 1 Differentiate both sides of the equation, getting D ( x 2 xy y 2) = D ( 1 ) , 2x ( xy' (1)y) 2 y y' = 0 , so that (Now solve for y' ) xy' 2 y y' = 2x y, (Factor out y' ) y' x 2y = 2 x y, and the first derivative as a
