## anonymous 4 years ago Essay: Show all work. Find the following quotient: 25x^2-100y^2/5x+10y

1. anonymous

Difference of 2 squares in the numerator, can you factor those?

2. anonymous

what do you mean

3. anonymous

$a^2-b^2=(a-b)(a+b)$

4. anonymous

look familiar?

5. anonymous

yes but i never know how to plug the numbers in

6. anonymous

what is$\sqrt{25x^2}$

7. anonymous

5x^2

8. anonymous

close

9. anonymous

what is$\sqrt{x^2}$

10. anonymous

x^1.41

11. anonymous

$\sqrt{x^2}=x$

can you explain that rick? and then retrice natz the original question?

14. anonymous

huh dgo

15. anonymous

i typed a s s k i think

anyhow I am wondering what you are taking away from all the answers youve been getting. are you learning how to do this stuff?

17. anonymous

yes i have learned a lot from this website i just have a hard time grasping it .It takes me to learn it mre than once before i got it all the way

18. anonymous

your answer is 5x-10y use difference of squares to simplify into: $(5x+10y)(5x-10y)\div(5x+10y)$ (5x+10y) crosses out from the equation because $(5x+10y)\div(5x+10y)=1$ so you are left with 5x-10y

19. anonymous

same for me natz haha ive learned a lot from this website, just takes me so long

20. anonymous

it is just math is my worst subject

21. anonymous

addrigonzalez is that the whole problem

22. anonymous

23. anonymous

it should be, you are looking for a quotient, right? so if 6 is divided by 3, the quotient is 2

24. anonymous

yes they cross out eachother

25. anonymous

i love math, we are on derivatives in college and i just dont understand my foreign teacher or whay we even need derivatives in the first place

26. anonymous

derivatives are unnessecary
