Factorise : 6x2 - 5xy - 4y2 + x + 17y - 15 |

Answer» 6x2 + x[1 - 5y] - [4y2 - 17y + 15] = 6x2 + x[1 - 5y] - [4y2 - 17y + 15] = 6x2 + x[1 - 5y] - [4y(y - 3) -5(y - 3)] = 6x2 + x[1 - 5y] - (4y - 5)(y - 3) = 6x2 + 3(y - 3)x - 2(4y - 5)x - (4y -)(y - 3) = 3x[2x + y 3] - (4y - 5)(2x + y - 3) = (2x + y - 3)(3x - 4y + 5) |
