The LCM of the equation is correct. It being \(\bf{2x(4x+3)}\) but it was applied to the parenthesis incorrectly. \(\large\bf{2x(4x+3) \times (\frac{-5}{4x+3} + \frac{3}{2x} = \frac{17}{8x^{2}+6x})}\) You apply the LCM to each fraction. \(\large\bf{(\frac{-5}{4x+3} \times 2x(4x+3)) + (\frac{3}{2x} \times 2x(4x+3)) = \frac{17}{8x^{2}+6x} \times 2x(4x+3)}\) Simplify and you'll see how it differs to `Step 2`.

hiya:

@563blackghost thank you so much for your help!!!!

563blackghost:

ah no problem cx

hiya:

I have another question will you help me answer it?

563blackghost:

i can look at it, sure cx

hiya:

I can't see the whole answer for the 1st question

563blackghost:

\(\bf{(\frac{-5}{4x+3} \times 2x(4x+3)) + (\frac{3}{2x} \times 2x(4x+3)) = \frac{17}{8x^{2}+6x} \times 2x(4x+3)}\) im rusty with my latex x.x its been a while.

hiya:

lol thank you do I just copy paste the answer?

563blackghost:

well i would suggest putting it into your own words. I mean, do you understand the explanation I gave you?

hiya:

yes I do

hiya:

i'll close this post and open an another one

563blackghost:

I mean it's basically an error in the distribution of the LCM. \(\bf{Distributive ~Property}\) \(\bf{a(b+c)=ab + bc}\)

563blackghost:

welp ab + ac*

hiya:

ok thank you!

563blackghost:

ur second question?

hiya:

I'll post it in an another question and will mention you

563blackghost:

okay
