Thanks to the both of you. I totally forgot about the setting equal to zero part and NOT -6. By setting it equal to -6 that is no longer a root...so you're right again. |

there is a funny disproval of a fundamental axiom of euclidian geometry.
in highschool, you learned: there can be only one straight line passing through two given points, right? take Earth, for example, and it's south and north pole. you can draw as many lines (meridians) through them as you wish... |

yes. regardless of what you'll think, this is purely logical and math-related problem:
two old friends from back in college days meet:
-so how are you? got any children
-three, actually
-how old are they?
-well, the sum of their ages is the number of windows in that building.
-hmmm... that's still isn't enough.
-the oldest son has black hair.
-now i know the answer. your children are.......
so how old were his children? (once again, this utilizes nothing but logic and very simple math;)) |

way over my head.
he has none!! windows aren't IN buildings, they are ON buildings!! |

reminds me of work today.
My boss tells me to find the weight(lb) of a piece of zircar(insualtion) based on his dimensions. Easy... Volume*density of zircar = weight !!!
He had autodesk inventor that by typing in the density of zircar and selecting the piece it will determine the wiehgt. So he did and compared it my answer. It was different. How could the this fundamental formula fail me compared to the computer. Well it was right in front of us. He had two holes in his insualtion that I forgot subtract from the volume duhhh. Sometimes putting your hand to paper will not solve a problem. It will be right in front of you:wtf: |

x^3 - 4x^2 + x + 6 = 0
hmmm dag I took numerical methods to solve ish like this up the nth degree. My school notes are at work though. Lunch if I remeber I will post some ish |

therefore (derivative), 0=3x^2 - 8x +1
i think... it's been a while... :D |

here's one:
disprove the pythagorean theorem. |
draw a triangle on the sphere and the sum of angles is > 180; inside a sphere < 180
as for the original problem, you can look at the derivatives no? |

the derivatives will tell you the critical points (and second derivatives - points of inflection), but not the roots. |

whats the answer to the logic test??
another problem. somebody factor 6x^2 + x - 1 |
