Hello,
Help! I am stuck again
Okay, I vaguely remember how to factorize the following:
0 = 2x^2 + 5x - 7
The above is easy since all we have to do is find two numbers that when multiplied together gives us -14, and
we have to find two numbers that when added together gives us 5, hence, 7 and -2!
So it becomes:
(2x+7) (x-1)
Now I need to do the same factorization but for this:
114 = -0.026x^2 + 1.928x + 90.96
-0.026x^2 + 1.928x -23.04 = 0
Here, I have to find two numbers that when multiplied together gives us (0.026*-23.04) 0.59904 and
we have to do is find two numbers that when added together gives us 1.928... how do I find that
Is there a mathematical tool in Excel that can do this for me?
Once I can factor my equation I can come up with an equation where I can solve for x every time!
So no matter what y is, I can plug y into an equation and figure out x.
thanks for your help!
