matrix elimination1 Attachment(s) What do you guys suggest to solve this question,please? |

if elimination fails then the matrix has no inverse and thus it's determinant is 0. solve the resulting quadratic for it's two roots |

By inspection (using Romsek's idea) I'd say that zero and 3 are the numbers you are looking for. |

ok now I totally understand how to solve it. thanks :) |
