Hi I am trying to teach myself maths. So go easy on me if these are stupid questions.
I have the equations
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
a= 1
b= -2
c= 1
a = 1
b = 2
c = +1
???
Is that correct?
