For this question, you have to use the distribution rule. So you would do 5X3x which equals 15x. Next you would do 5X-4 which equals -20. So now you have 15x – 20. Next you would do -6X4 which equals -24. Next you would do -6X-3x (negative X negative always equals to a positive) which equals 18x. So now your question should look like this. 15x – 20 -24 + 18x. Now you collect like terms so you would do 15x + 18x which equals 33x. Next you would do -20 – 24 which equals -44. So your final answer is 33x -44.

This is from the unit polynomials, which was not hard for me because I got to understand it very well and I’m proud about my mark on the test. I could improve my grade in semester 2 by studying first before doing anything else so I get an A on my tests and quizzes.
