1. Find the solutions, or estimated solutions, if they exist, of the quadratic equation x29x+20.25=0 by graphing y=x29x+20.25.
Use zoom tool, if neccessary, to find the points where the graph crosses the x-axis, where y equals 0- this will be the solution(s).

2. The solutions to the equation x29x+20.25=0 occur where the graph crosses the x-axis, at the point the y value is 0.
The graph crosses the x-axis at the points(4.5,0). The only solution is x=4.5
3. Check that 4.5 is a solution. Replace 4.5 for x in the equation x29x+20.25=0
x29x+20.25=(4.5)29(4.5)+20.25
=20.25-40.5+20.25=0
This is a solution

Is it true that vector spaces are defined to check if system of linear equations is solvable or not?
Explanation: Goal is to solve system of linear equations.
In matrix form: X=b. As A=[C1C2Cn], where Cn is a column and x=[x1x2xn].
Therefore, C1x1+c2x2++Cnxn=b. Linear combination of column vectors produce vector b.
Because of above statement (linear combination) we choose a set of vectors that have closure under addition and scalar multiplication (closure under linear combination) and call that set of vectors a vector space. Now, if vector b lies in that set of vectors (vector space) then only system of linear equations is solvable.

Technique for solving ax+bcx+d=px+qrx+s where the sum of numerators equals the sum of denominators
I was looking up some shortcuts to solve quadratic equations. I got a technique that applies when the sum of the numerators and denominators are equal, but I am unable to understand the reasoning behind it. Here I'm showing an example:
3x+46x+7=5x+62x+3
