Solve the equation.
3x2 - 5x - 8 = 0

x = 3/8, x = -1
x = 3/8, x = 1
x = 3/8 , x = 0
x = 8/3, x = -1

x = -5, x = 8
x = -5, x = - 8
x = 5, x = - 8
x = -40, x = 0

we have all seen these collections of numbers in large brackets. But what exactly is a matrix?
Is it just a collection of scalar numbers or vectors?
I have seen in some textbooks the 'name' of the matrix given in bold letters but in some places not.

So what exactly is it?

1/0 = undefined


.999999999 repeating = 1

therefor,

.0000000 . . . infinite zeros . . .0001 = 0

therefor,

1/infinity = 0

and

1/(1/infinity) = infinity

so

1/0 = infinity

So are "infinity" and "undefined" the same thing?
