haha sorry I overlooked your question..
"i do not know how to write the equasion on the keyboard could you please help me and explain it to me in lamens terms.....99990 Larson and Hostetler Elementary and intermediate Algebra fourth edition pg.627 #29 I have tried to figure this out i have done it over and over and can not figure it out so could you please help me"
You'll have to repost the question so perhaps someone else can answer it who may have the book, excuse me for my quick answering.
Although, perhaps I can help you with writing the equation on the keyboard
BASICS:
* is multiply, times
+ is add, plus
/ is divide, by
- is subtract, minus
NOT SO BASICS:
x^2 means squared, x^5 means x to the power of 5.
use parentheses to denote where to start.
(3+5)*2 means 3+5 and then the answer times 2, which altogether equals 16, while
3+5*2 means 5*2 and then plus 3, or 13.
lastly, you can use { { { problem here } } }, without the spaces between the brackets. [replace 'problem here' with your problem, no spaces before or after].
Perhaps, as I am completely unaware of your situtation, you have no number keyboard. In that case, copy the following by highlighting it and pressing CTRL&C to copy and CTRL and V to paste [hold control and press the letter c or v]. 1 2 3 4 5 6 7 8 9 0 ! @ # $ % ^ & * ( ) _ + | - = \
There, you now have a numeric keyboard. You can also go to the calculator program in windows and copy any number you click into there.
If I still haven't answered you question, please write the question on the post just as it is in the book, and then write it between 3 brackets.
Lastly, if you have a graph, this will show you how to get it in:
"You can use { {{ formula } }} notation to insert nice looking formulas into the text of your solution. Example: {{ {x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} would result in this formula: 
. Create a graph by saying {{ { graph( 300, 200, -6, 5, -10, 10, x-2, x^2/10-x) }}} (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions x^2 and x^2/10-x)."
Lastly, try one of the solvers, if this is algebra, they would be of much help.
