Similarities: They both are polynomials of degree 2, both of their graphs is a parabola, both have either 2 or 0 real solutions, they are both continuous functions over R
(DOS= difference of two squares, PST=perfect square trinomial
Differences: PST has three terms, whereas the difference of squares has 2. PST's factors are both the same, whereas DOS's elements are conjugates of each other. DOS can always be factored into two distinct polynomials with rational coefficients, whereas PST has two same polynomial factors.

6 × 4 × 5 × 2 = 240 different possible bundles

Knowledge point:

The Product Rule: If there are n ways to do A and m ways to do B, then the number of ways to do A and B is n × m

I.e. to get the amount of different bundles, all the relevant amount of options for each category must be multiplied by each other.

What is the axis of symmetry for f(x) = −5x2 − 20x − 10

Tasya [4]

For this case we have the following function:
 $f(x) = -5x^2 - 20x - 10
$
 To find the axis of symmetry, the first thing to do is to derive the function.
We have then:
 $f '(x) = -10x - 20 
$
 Equaling zero we have:
 $-10x - 20 = 0 
$
 We clear the value of x.
We have then:
 $-10x = 20 

x = -20/10 

x = -2 
$
 Answer:
The axis of symmetry is given by:
x = -2
