What is the quadratic equation and what does it do?
In: 287
The quadratic equation is a specific way to define a relationship between two values.
In the case of the “quadratic”, the relationship specifically has to do with the one value being related to the “square” of the other value – such as “9” is “3” squared.
That and a little bit more – it is related to the square of the if value, plus the value, plus some fudge factor.
There are other specific types of relation ships as well
The blue car was going twice as fast as the red car – this is a “linear” relation
The area of a circle is proportional to the square of its radius – this is a “quadratic” relation. Allow me to explain.
Area = (pi) * r^2 + (0)*r + 0
Here, your “a” is pi, “b” is 0 and “c” is 0
There are other types of relations as well, such as “exponential”. This can be like – the number “10,000” is the the number “10” times itself many times! (In the event that it is related to the other number times itself once, we call it “quadratic”. )
Here are some relation examples as an example
50 = 5*x is linear (x is 10)
200 = 2*x^2 is quadratic (x is 10).
10,000,000,000 = 10^x is exponential (x is 10)
NOTE: a quadratic equation can have linear” component (b*x), and a constant (c) it doesn’t have to.
