Best ResponseYou've already chosen the best response.3this is an exercise in completing the square first divide the coefficient of x ( that us the 3) by 2 and write x^2  3x  1 = ( x  1.5)^2 2.25  1 = 0 the 2.25 comes from when you square 1.5 it becomes 2.25 so you have to subtract 2.25 to square things up

Best ResponseYou've already chosen the best response.3no i dont get that lets see x  3/2 = +/ sqrt13/2 = 3/2 + sqrt13/2 or 3/2  sqrt13/2 = 3 +/ sqrt13  2
