\[\frac{ 5x \sqrt{3} }{ \sqrt{48} x^2 }\]
Is this what you mean?

yea

First we need to simplify the bottom radical, can you think of any factors of 48?

any factors that involve a 3?

|dw:1369417374702:dw|

3*16=48

Yup, now are any of those a perfect square?

i dont kno what tht means

Like are any multiplied by the sane number.. such as 1*1=1, 5*5=25, 6*6=36, etc

oh then yes

which would that be?

wait there isnt

actually there is.. the 16? 4*4=16

oh kk

Now you can simplify it down and that's your answer

47. 5 sqrt x/4x

Or 5/4x

can u help me with 1 more?

Sure

which of these graphs show the quadratic function y=2x^2+8x+7?

I'd say it's graph B
