dy/dx=(three (x^ two +y^ two))/x(x^ two +3y^ two +6y)
dy divide by dx equally (3(x squared plus y squared )) divide by x(x squared plus 3y squared plus 6y)
dy divide by dx equally (three (x to the power of two plus y to the power of two)) divide by x(x to the power of two plus 3y to the power of two plus 6y)
dy/dx=(3(x2+y2))/x(x2+3y2+6y)
dy/dx=3x2+y2/xx2+3y2+6y
dy/dx=(3(x²+y²))/x(x²+3y²+6y)
dy/dx=(3(x to the power of 2+y to the power of 2))/x(x to the power of 2+3y to the power of 2+6y)
dy/dx=3x^2+y^2/xx^2+3y^2+6y
dy divide by dx=(3(x^2+y^2)) divide by x(x^2+3y^2+6y)
