10n3 − 15n2 + 20xn2 − 30xn Part A: Rewrite the expression by factoring out the greatest common factor. (4 points) Part B: Factor the entire expression completely. Show the steps of your work. (6 points)

(5n^2+10xn)(2n-3)

Step-by-step explanation:

Group the first two terms and the last two terms together.

Factor out the common factor.

In the first two terms, the GCF is 5n^2.

In the last two terms, the GCF is 10xn

5n^2(2n-3)+10xn(2n-3)

Now factor out (2n-3)

(5n^2+10xn)(2n-3)

(5n^2+10xn)(2n-3)

Step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
