Best ResponseYou've already chosen the best response.0you can simply calculate the discriminate \[b^{2}  4ac\] by putting the equation in the form \[y=ax^{2} + bx +c\]

Best ResponseYou've already chosen the best response.0firstly expand the equation to standard for i.e \[a x^{2} +bx +c\] which in this case is \[4x^2 +24x 28\]

Best ResponseYou've already chosen the best response.0no they are not coordinates it tells u the nature of the roots whether they are real or imaginary

Best ResponseYou've already chosen the best response.0then use the formula for discriminant as @Avva has suggested to find value of discriminant a=4, b24, c= 28

Best ResponseYou've already chosen the best response.0No if the question asks for discriminant you just have to tell the numerical value of \[[b^2  4ac] \]

Best ResponseYou've already chosen the best response.0@zainulafaq so is it 130 and my work is shown below @zainulafq 24^24(4)(28) 576+16(28) 576448=130

Best ResponseYou've already chosen the best response.0all of it is excellent except for last step . . 576448 = 128 not 130 . . .
