Nakim simplified 3 times the square root of 2x plus x times the square root of 8x minus 5 times the square root of 18x and got -10x times the square root of 2x for an answer.

Question

mikezack123 · Answer

Part 1: Using complete sentences, explain what Nakim did wrong. 

Part 2: Show all your work to simplify the expression. 

(You can use "sqrt()" to show a square root. For example, 7 times the square root of a can be written as 7sqrt(a). )

whats your explanation?

mikezack123 · Answer

what do you mean? @amistre64

amistre64 · Answer

did you read the question?

mikezack123 · Answer

yes why?

amistre64 · Answer

if you cant determine part1 yet, then how would you work part 2?

mikezack123 · Answer

i didn't do any part of the question yet

amistre64 · Answer

im trying to get you to develop a solution without actually giving you the answers.  guidance as opposed to direct answers

amistre64 · Answer

try to work the question then ....

mikezack123 · Answer

i don't know where to start thats why i posted it on this website

i wish i could help but i can't figure it . sorry.

amistre64 · Answer

id start with part 2 ... just becuse i know how i would simplify the problem

mikezack123 · Answer

@princess6324 thanks anyways :)

amistre64 · Answer

i think the 2x part is right, since the sqrts can all simplify to a 2x part and factor out a complete square

amistre64 · Answer

3sqrt(2x) + xsqrt(8x) - 5sqrt(18x)  and got -10x sqrt(2x) 

putting it in the format migh thelp me see it better ... flipping between windows and trying to keep things staight is hard on these old eyes

amistre64 · Answer

can you factor out the perfect squares from out of the sqrts?

"Nakim simplified 3 times the square root of 2x plus x times the square root of 8x minus 5 times the square root of 18x and got -10x times the square root of 2x for an answer. "

$$3\sqrt{2x} + x\sqrt{8x} - 5\sqrt{18x} = -10x\sqrt{2x}$$

Can you factor all of the things under the square root signs?  Are there any perfect squares which can be factored out?
