1. ## Factorising?

Hello folks,

Have not done any maths in a couple of years and now an assignment has lead me to a mental blank. I have to solve 1000 = 0.7Ts - 205.1 + 6.804Ts^4 - 5.01 for Ts obviously. The second Ts is to the power of 4 for clarity.

How do I do this? I know it is simple but am a bit rusty...

Any help greatly appreciated.

Regards Paul.

Dear Paul,

Is this what you mean??

$\displaystyle 1000 = 0.7T_{s} - 205.1 + 6.804T^{4}_{s} - 5.01$

3. Yes - that is precisely what I mean. How do you make it appear like that? And secondly what is the answer to the equation?

4. $\displaystyle 1000 = 0.7T_{s} - 205.1 + 6.804T^{4}_{s} - 5.01$

Move the $\displaystyle 1000$ to the right side; the whole equation now equals $\displaystyle 0$.

$\displaystyle 0 = 0.7t_{s} - 205.1 + 6.804t^{4}_{s} - 5.01 - 1000$

Rearrange into the form $\displaystyle ax^2 + bx + c$.

$\displaystyle 0 = 6.804t^{4}_{s} + 0.7t_{s} - 205.1 - 5.01 - 1000$

$\displaystyle 0 = 6.804t^{4}_{s} + 0.7t_{s} - 1210.11$

This expression cannot be simplified any further.

To write equations in this format, go to http://www.mathhelpforum.com/math-help/latex-help/ and read the Latex tutorials. You can click on the equations in my posts to view the source code that was used to format them.

5. The answer for Ts is a whole number, so somehow this can be done. I am not sure how. Is there software available? Can anyone else add anything to this?

Regards Paul.

Dear Paul,

Of course there are software for fatorizing. Let me give you a useful website!!
