Best ResponseYou've already chosen the best response.0@dominique2525 Thats not one of the options. These are the options: {1/2,2/3} {1/2,2/3} {1/2,3/2}

Best ResponseYou've already chosen the best response.1I think there is a significant error in the calculations \[x =\frac{ 7 \pm \sqrt{(7)^2  4 \times 6 \times 2}}{2 \times 6}\] which becomes \[x = \frac{7 \pm \sqrt{49  48}}{12}\]

Best ResponseYou've already chosen the best response.1and just to show your teacher, this quadratic can be factored multipily a and c 6 x 2 = 12 find the factors of 12 that add to 7.... they are both negative 3, 4 then write the factored equation as (6x 3)(6x 4)  6 factor the linear factors 3(2x 1) 2(3x 2)  6 remove the common factors (2x 1)(3x 2) = 0 now you can find the values

Best ResponseYou've already chosen the best response.1well to get the solution simplify the square root \[x = \frac{7 + \sqrt{1}}{12}~~~~and~~~~~ x = \frac{7  \sqrt{1}}{12}\] what is the value of \[\sqrt{1} = ?\]

Best ResponseYou've already chosen the best response.1great so you have 2 answers \[x = \frac{7 + 1}{12} ~~~~and~~~~x = \frac{7 1}{12}\] just simplify them

Best ResponseYou've already chosen the best response.1you made the calculation error inside the square root (7)^2  4 x 6 x 2 you someone posted 49  48 = 97 it should 49  48 = 1
