What do you need to do?

What are your thoughts?

Northing:

x2 - 12x + 32 = 0
I'll call this Equation A.

x2 - 6x = -9

x2 - 6x + 12 = 3
These two are equivalent. I'll call them Equation B.

x2 = 12x - 36
I'll call this Equation C.

-21 = -10x + x2
I'll call this Equation D.

Westing:

x3 - 6 = 6x2 - 11x
This will be Equation E.

627.552601 = 50.102x - x2
And this is Equation F.

So you appear to have six equations in one variable. This should be soluable, though it is more likely that there is no solution.

What is the meaning of "Northing" and "Westing"? What generated these equations? What efforts have you made thus far?

For instance, Equation A solves simply by factoring (here), as does Equation C. But the solutions for Equation A are x = 4 and x = 8, while the solution to Equation C is x = 6. There being no shared solution value, this "system" has no solution at all.

When you reply, please include the full and exact original exercise statement, the complete instructions, a detailed description of any graphical or other outside information, and a clear listing of your thoughts and efforts so far. Thank you! :wink:

What are your thoughts? What have you tried? How far have you gotten? Where are you stuck?

For instance, you plugged the coefficients into the Quadratic Formula (here), simplified, and... then what?

Please be complete. Thank you! ;)
