I think you're factoring this...? You can do that by grouping here. Put the 4 terms in groups of 2 and factor out the greatest common factor. What's left behind is a common binomial factor that can also then be factored out. Like this:

Factoring what we can out of both sets gives us this:

The 2n-5 is a common factor between both the sets of terms, which in turn can also be factored out:

I'm not exactly sure what you are doing with this, but we can keep factoring for the sake of completeness. The 5 n-squared term can also be factored:

and

and

so

. Simplifying that down its simplest is this:

So your three factors for that polynomial are

Answer:
Two straight lines with slopes m and m' are parallel when m = m'
Two straight lines with slopes m and m' are perpendicular when m × m' = - 1.
Step-by-step explanation:
Let us assume that the two non-vertical lines in the slope-intercept form are
y = mx + c ........... (1) and
y = m'x + c' ............ (2)
If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'
Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)

Answer:
a (3,-1)
Step-by-step explanation:
The number that "completes the square" is the square of half the x-coefficient, (-6/2)^2 = 9. Rearranging the given function to include the square trinomial, we have ...
f(x) = x^2 -6x +9 -1 . . . . . . . here, we have 8 = 9 - 1
f(x) = (x -3)^2 -1 . . . . . . . . . . vertex form
Comparing this to the generic vertex form ...
f(x) = (x -h)^2 +k . . . . . . . vertex at (h, k)
we see that h=3 and k=-1.
The vertex is (h, k) = (3, -1).
1520 ÷ 10 = 152
1520 ÷ 20 = 76
1520 ÷ 40 = 38
Jonah recorded the points his team scored during its last nine basketball
games. The mean number of points scored was 42 and the MAD Was 4.4.
The MAD shows that the scores generally varied greatly from the mean.
The scores were mostly less than
38 (42 -4.4 = 37.6)
greater than
46 (42 + 4.4 = 46.4).
