Needing a math wizz. :D

[I AM NOT THAT GUY 5,715]

(x+1)(x-1)(x+1)(x-1)

Show off!

He, who is he? I am a female. I never said the problem was hard - but it is hard for me, I am just starting to relearn this stuff and it's been years since I have taken a math class. Give me a little credit. Thanks for the help. I will keep you in mind the next time I need help.

You Go Gurrl! Don't listen to the neigh-sayers, it will come back to you. It might take a bit longer than before and it might seem hard at first, but it will come, hang in there!

Thank you so much!!

The second is wrong. You factored wrong.

Hint: Your factors on the top left is not correct. It should be (x+4)(x-3).

Would help the OP to show how you got that answer.

That term is (X^2 + X - 12)

for factoring take the square root of the first term, and look for integers in the last term, so that the middle term is the is twice the product of the the two terms in each set.

like (x+/-) (x+/-) with possible integers of (-12), 1, 12;, 2, 6; 3, 4. with either the first or second number having a negative sign in front of it. With practice, this comes quicker, but since the coefficient of the center X term is 1, the difference between the two integers has to be 1, the only set with that difference is 3 and 4, and since the center term is positive, the 4 has to be positive and the 3 negative so their product is a -12.

Therefore, (x+4)(x-3) is the only possible solution when multiplied out equals, x^2 -3x +4x -12 or (X^2-x-12).

It takes practice. I cheat with Mathcad, a TI-89, simulation programs, as nobody want to pay an engineer minimum wages to work math out by hand.

Instead of using the long method (completing the square), I used a shortcut first. That is how I solve computer programming problems. You want to reduce CPU time as much as possible. So, to do the shortcut, you look at the second and third term. This only works if the first term has a co-efficient of 1. You would take two numbers that multiple to get the third term, and when those two numbers add or subtract you will get the coefficient for the second term. That is the shortcut.

If this doesn't work, you use the completing the square method. The quicksort algorithm in computer programming follows a procedure median of three with a cutoff of x, where x determines whether it's faster to use an insertion sort or not. Similar to this concept.

I love MathCAD to factor large things.

Wow Neil, impressive! If the system was overclocked 1x and the system was raided what would the answer be?

[Niels Bohr 72]

ROFL!

It is faster. I can do these factors without using completing the square. There are shortcuts. Just like computing huge matrixes. Using dynamic programming, you can figure out ways of using a table to store known data instead of re-computing the same data. This eliminates multiple FOR loops, and recursive algorithm which would take more time than dynamic programming.

Its okay, you can just say I don't know.

It has been many, many years since I did this, and I need a refresher course, but if you're trying to make the expression undefined in the first question, shouldn't X equal either 9 or -2 instead of making x NOT equal to either of them?

[SuperDuper! 230]

Console Master, you appear to be a mathematical prodigy as well.

Can you give me the calculus formula for the amount of pressure required to remove a brassiere with one hand? I'm trying to prepare for a hot date!

does your wife know about this?

[SuperDuper! 230]

does your wife know about this?

She is gonna be here soon, so I will be preparing

Oh, and nevermind, CM, I did a little scribbling on a napkin and figured out the bra popping formula, where you simply calculate the woman's breast mass by inverting the Laplace Transforms, and by dividing by two the properties of the limits, derivatives and integrals of the density or perkiness of the bazooms. Heck, here is the formula, it speaks for itself.

From what I know inorder to make it undefined it has to be any other number besides 9 and -2... but not sure.
