This is the last one for now. I hope you guys are on when I take my quiz because there are two problems like this on that I can't get. 1/9x^2+11/3x=432

Best ResponseYou've already chosen the best response.0This is just like the last problem except where there was 80 you put 432

Best ResponseYou've already chosen the best response.0multiply every term by x^2 and then solve using the quadratic formula.

Best ResponseYou've already chosen the best response.0i think the x^2 is suppose to be in the numerator

Best ResponseYou've already chosen the best response.0adfriedm I believe the x^2 is on top... just guessing.

Best ResponseYou've already chosen the best response.0I don't get the quadratic formula. To me it doesn't make sense

Best ResponseYou've already chosen the best response.0you can find that formula if you complete the square for ax^2+bx+c=0 so it makes perfect sense

Best ResponseYou've already chosen the best response.0is it (1/9)x^2+(11/3)x=432 or 1/(9x^2)+11/(3x)=432?

Best ResponseYou've already chosen the best response.0of course it requires a to be nonzero

Best ResponseYou've already chosen the best response.0rihgt! because the quadratic formula is undefined for a=0

Best ResponseYou've already chosen the best response.0well moreover because the proof doesn't follow with a=0

Best ResponseYou've already chosen the best response.0I think what confuses me and I know this is stupid. What is the + sign with the line under it?

Best ResponseYou've already chosen the best response.0it means you have 2 annswers one with + and one with minus

Best ResponseYou've already chosen the best response.0Ok but how do I work this if I have a + and  answer. I'm sorry I just don't get it

Best ResponseYou've already chosen the best response.0\[{b+\sqrt{b^24ac}}/(2a) and ( b\sqrt{b^24ac})/(2a)\]

Best ResponseYou've already chosen the best response.0it is the a quadratic equation, so we always expect 2 values which make it zero.

Best ResponseYou've already chosen the best response.0\[\frac{1}{9 x^2}+\frac{11}{3 x}=432 \] Put the 432 on the left hand side of the equation and combine terms into one fraction. \[\frac{1+33 x3888 x^2}{9 x^2}=0 \] If the fraction is zero, the Numerator is zero. Factor the Numerator and set the result to zero. x = 1/48 and x = 1/81
