Best ResponseYou've already chosen the best response.0multiply both sides by\(x^2\) and solve the resulting quadratic equation.

Best ResponseYou've already chosen the best response.1\[x^2/ x^2 + x^2/x^2 = 6x^2\]

Best ResponseYou've already chosen the best response.0the denominator of your second term above is wrong

Best ResponseYou've already chosen the best response.0you should get:\[x^2/ x^2 + x^2/x = 6x^2\]

Best ResponseYou've already chosen the best response.0next  simplify each term

Best ResponseYou've already chosen the best response.1but dont they need to have the same denominator to add

Best ResponseYou've already chosen the best response.0what does \(x^2/x^2\) equal?

Best ResponseYou've already chosen the best response.0correct  now simplify the next term

Best ResponseYou've already chosen the best response.0thats right  now rearrange this into a standard form, i.e into the form \(ax^2+bx+c=0\) and then solve

Best ResponseYou've already chosen the best response.1so I did quadratic equation and go 1 plus or minus radical 25 all over 12

Best ResponseYou've already chosen the best response.0doesn't look right  can you please show your steps so that I can help spot where you may have made a mistake?

Best ResponseYou've already chosen the best response.1k, u said put it into the standard form so I started from 1 + x = 6x^2 6x^2 + x+1 = 0 a= 6, b= 1, c= 1 \[1\pm \sqrt{1^{2}4(6)(1) \over 2(6)}\]

Best ResponseYou've already chosen the best response.1then got 1 plus or minus radical 25 all over 12

Best ResponseYou've already chosen the best response.0oh  sorry  I misread

asnaseer

Best ResponseYou've already chosen the best response.0you are right  and you know what \(\sqrt{25}\) equals?

asnaseer

Best ResponseYou've already chosen the best response.0the formula you used doesn't look quite right, it should be:\[x=\frac{b\pm\sqrt{b^24ac}}{2a}\]

asnaseer

Best ResponseYou've already chosen the best response.0the WHOLE thing should be divided by 2a

asnaseer

Best ResponseYou've already chosen the best response.0so you should have got:\[\frac{1\pm \sqrt{1^{2}4(6)(1)}}{2(6)}\]

Best ResponseYou've already chosen the best response.1o ok so um x = 1/3 and x = 1/2

Best ResponseYou've already chosen the best response.1ya I ment to put all over 2a but I was trying to make it come out nice and pretty in the equation thing but it took lng

asnaseer

Best ResponseYou've already chosen the best response.0although you should write it as: x=1/3 or 1/2

asnaseer

Best ResponseYou've already chosen the best response.0you don't usually put the minus sign in the denominator

Best ResponseYou've already chosen the best response.1wow these are so frustrating I was literally about to give up and go home, im in a library trying to study and there are all these other students basically hanging out and talking and there are no available tutors

asnaseer

Best ResponseYou've already chosen the best response.0also note that you should use the word "or" rather than "and" here. i.e. x = 1/3 or 1/2 instead of x = 1/3 and 1/2 because x canot equal both values at the same time

Best ResponseYou've already chosen the best response.0great  and keep persevering  you'll get the hang of these very soon I'm sure :)
