((2x²+y﹚²-5y²(3x²+1)-4(x²+y)(x²-y))÷5x²y

((2x²+y﹚²-5y²(3x²+1)-4(x²+y)(x²-y))÷5x²y
((2x²+y﹚²-5y²(3x²+1)-4(x²+y)(x²-y))÷5x²y

((2x²+y﹚²-5y²(3x²+1)-4(x²+y)(x²-y))÷5x²y
((2x²+y﹚²-5y²(3x²+1)-4(x²+y)(x²-y))÷5x²y
=(4x^4+4x²y+y²-15x²y²-15y²-4(x^4-y²))÷5x²y
=(4x^4+4x²y+y²-15x²y²-15y²-4x^4+4y²))÷5x²y
=(4x²y-15x²y²-10y²)÷5x²y
=4/5 - 3y -2y/x²
