The bean trees summary
Subject:
T he Bean Trees opens in rural Kentucky. The novel’s protagonist, Taylor Greer, who is known at the beginning of the novel by her given name, Marietta, or by her nickname, Missy, remembers a moment in her childhood when Newt Hardbine’s father was thrown to the top of the Chevron sign after his tractor tire exploded. Ever since then, Taylor has been afraid of tires. Taylor goes on to tell the story of Newt Hardbine, a peer of Taylor’s who died while Taylor was still in high school. Although Newt and Taylor seemed like identical kids when they were small, Taylor was the one to escape small-town life. She did so by avoiding pregnancy, getting a job working at the hospital, and saving up enough money to buy herself an old Volkswagon bug.
Quadratic Equations
Subject:
Quadratic Equations
This is what a "Standard" Quadratic Equation looks like:
•The letters a, b and c are coefficients (you know those values). They can have any value, except that a can't be 0.
•The letter "x" is the variable or unknown (you don't know it yet)
Here is an example of one:
The name Quadratic comes from "quad" meaning square, because the variable gets squared (like x2).
It is also called an "Equation of Degree 2" (because of the "2" on the x)
More Examples of Quadratic Equations:
In this one a=2, b=5 and c=3
This one is a little more tricky:
•Where is a? In fact a=1, as we don't usually write "1x2"
•b = -3
•And where is c? Well, c=0, so is not shown.

How to use
To change the values of the coefficients, use the "+" and "-" buttons under each value. The buttons change the value by 0.1 at each step. Holding a button down causes this action to be repeated.
Click the "Clear" button to reset all values to the default values, a=1 and all other values are 0.
