First expand the brackets, collect like terms and simplify.\n\n(-2x^2 + 5x - 1) - (3x^2 - 4x - 6)\n= -2x^2 + 5x - 1 - 3x^2 + 4x + 6\n= (-2 - 3)x^2 + (5 + 4)x + (-1 + 6)\n= -5x^2 + 9x + 5

5y(y^2 - 5xy - 14x^2)\n\nIf you're expanding, you get:\n\n5y^3 - 25xy^2 - 70yx^2\n\nIf you're factoring, you get:\n\n5y(y^2 + 2xy - 7xy - 14x^2)\n= 5y( y(y+2x) - 7x(y+2x) )\n= 5y(y + 2x)(y - 7x)
