Trying to factor a multi variable polynomial
2.1 Factoring kx - 2x2 - 7
Try to factor this multi-variable trinomial using trial and error
Factorization fails
Equation at the end of step

Solving a Single Variable Equation:
3.1 Solve kx-2x2-7 = 0
In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
We shall not handle this type of equations at this time.
Answer:
24.5
Step-by-step explanation:
A calculator or spreadsheet is good for doing this sort of computation.
_____
You add up the magnitudes of the differences between the given y-value and the corresponding value you get from the equation. For the first couple of points, these values are ...
... |3 - (0.1·1 +2.9)| = 0
... |2.5 -(0.1·6 +2.9)| = |2.5 -3.5| = 1
The computation proceeds like this for the remaining 6 points, and the numbers added. The result is 24.5.
A ratio equivalent to 3/20 can be 6/40 or even 9/60
