Hi I am trying to teach myself maths. So go easy on me if these are stupid questions.

I have the equations

$\displaystyle x^2 - x - 6$

I need to find out the values of A,B,C so I can plug them into the quadratic equation to find the roots.

The example in the book says

But I do not understand this,... dose this mean that the a,b,c forOk so for Example 1. where x^2 - x - 6

What are a, b, and c so we can plug them into the quadratic equation to find x?

(1)x^2 - (1)x - 6 = 0

Let's get it into the exact form of [ax^2 + bx +c = 0]

(1)x^2 + (-1)x + (- 6) = 0

a b c

therefore...

a = 1

b = -1

c = -6

$\displaystyle x^2-2x+1$

a= 1

b= -2

c= 1

$\displaystyle x^2+2x+5$

a = 1

b = 2

c = +1

???

Is that correct?
