"To the power of" You don't know that? such as 2^4 = 2 "to the power of" 4 = 16 3^2 = 3 "squared" etc. |

fish i guess your question is too hard for members, i saw it and it looks complicating. heres a easy one for the easy people. 5X+3=7X-2 X=? |

That was the main point. They're not even hard if you know what to do. x = (5/2) or 2.5 |

yeah you are correct, well if you know poblems like the ones you posted then you probably know many of the problems i will post inthe future, its just that i want to post easy ones so people post and then get higher in difficulty as we go. heres another 6X-23=5X+34 |

Those are all too easy.. plus they use the same principle. Here, at least do another type of algebra. x^2 + 6x = -9 (This will be easiest if you know how to factor) (Hint: move -9 to the left side to get x^2 + 6x + 9 = 0) |

its -6(big square root sign)6squared- 4(1)(-9)(end quotient)and all of this is divided by 2 thats the formula but i dont feel like doing it. though is it 360 |

You actually put it in the quad. forumla? It would've been easy to factor.. x^2 + 6x + 9 = (x+3)(x+3) = (x+3)^2 = 0 Therefore x = -3... Not 360 |

Your guess was 357 off though.. |
