Why x^2+25 does not factor?

There are several ways to factorize a term:

1. Extract the common factor

2. Factorization by formulae

3. Cross Multiplication

4. Grouping

I'm not sure I will be able to give you a satisfying answer, but asking this question is like saying why can't    be further simplified. You just can't, because it is the simplest form.

However, if it were , It could be factorized into .

Hope this clears up your confusion.

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
