Question 788798: hello, I am on the last question on an assignment. I have tried already but im not sure if what I have combined is right. can you please help me with this.
Nakim simplified 3*sqrt(2x)+ x*sqrt(8x)- 5*sqrt(18x)and got -10x times the square root of 2x for an answer.
Part 1: Using complete sentences, explain what Nakim did wrong.
Part 2: Show all your work to simplify the expression.
please help me. thank you so much.

---------------------------------
3*sqrt(2x)+ x*sqrt(8x)- 5*sqrt(18x)
----
3sqrt(2x) + x*2sqrt(2x) - 5*3sqrt(2x)
-----
= [3 + 2x - 15]sqrt(2x)
-----
= [2x-12]sqrt(2x)
