## swin2013 2 years ago Help my minor algebraic problem??

1. swin2013

\[x^{2}5.7x10^{-6}C = (.25+x )^{2} 3.5x10^{-6}\]

2. swin2013

I'm trying to find x. But I am not getting the answer correctly... mainly because of my algebra lol

3. jim_thompson5910

you're using two kinds of 'x' terms one is for the variable and the other is for multiplication is that correct?

4. swin2013

those are supposed to be -6. and C stands for coulombs... it's a physics problem but i just need help with the mathematics part lol

5. jim_thompson5910

ok C is just a unit so you can ignore it for now

6. swin2013

yes basically lol

7. swin2013

i distributed the 3.5 and isolated the x^2. but i still had an awry answer

8. jim_thompson5910

You'll have to use the quadratic formula because when you expand out the right side, you'll get a quadratic

9. swin2013

is there any faster method other than quadratic? because it's expected for me to solve this in like... a minute hahaha

10. jim_thompson5910

no you can't avoid solving it without using a graphing calculator or the quadratic formula because you have a quadratic on the right side

11. swin2013

oh nvm, i found a way to do it without quadratic formula. lol thanks though

12. jim_thompson5910

ok glad you found a way
