PLEASE HELP, THIS IS MY SECOND TO LAST QUESTION FOR THE YEAR SO I CAN PASS ALGEBRA (BRAINLIEST IF ANSWERED WITHIN 30 MINS AND CORRECT) An expression is shown below:

10n3 − 15n2 + 20xn2 − 30xn

Part A: Rewrite the expression so the GCF is factored completely. (4 points)

Part B: Rewrite the expression completely factored. Show the steps of your work. (6 points)

(5n² + 10xn)(2n - 3)

Step-by-step explanation:

10n³ - 15n² + 20xn² - 30xn

First step is to rearrange so that it can be grouped. We have

(10n³ - 15n²) + (20xn² - 30xn)

Next, we find the Greatest Common Factor of each of the part in the grouping, so that

5n²(2n - 3) + 10xn (2n - 3)

And lastly, we rewrite the factorised expression.

(5n² + 10xn)(2n - 3)

And this is the answer.

I hope you find the steps easy to understand.
