Best ResponseYou've already chosen the best response.0\[y=0.05x^2x+1 \] \[\begin{array}{*{20}c} {x = \frac{{  b \pm \sqrt {b^2  4ac} }}{{2a}}} & {{\rm{when}}} & {ax^2 + bx + c = 0} \\ \end{array} \]

Best ResponseYou've already chosen the best response.0if it was me, i would multiply everything by 20 and write \[x^220x+20=0\]

Best ResponseYou've already chosen the best response.0i know the formula but after i did it it looked wrong i got 1+(sr).8/.1

Best ResponseYou've already chosen the best response.0no it is just easier if it is not clear where i got the 20 from, lets clear the decimal by multiplying everything by 100 you get \[5x^2100x+100=0\] then divide by 5 and get \[x^220x+20=0\]

Best ResponseYou've already chosen the best response.0you really do not want to take square roots of decimals or divide by decimals use whole numbers

Best ResponseYou've already chosen the best response.0for \[x^220x+20=0\] it is probably easiest to complete the square because 20 is even i would write \[x^220x+20=0\] \[x^220x=20\] \[(x10)^2=20+100=80\] \[x10=\pm\sqrt{80}=4\sqrt{5}\] \[x=10\pm4\sqrt{5}\]
