the discriminant is 2128 do you want me to explain it as well?
you can simply calculate the discriminate \[b^{2} - 4ac\] by putting the equation in the form \[y=ax^{2} + bx +c\]
Please explain Sorry had bad internet
@zainulafaq is it 2128 or 128 ?
does the B and C stand as coordinates
firstly expand the equation to standard for i.e \[a x^{2} +bx +c\] which in this case is \[-4x^2 +24x -28\]
a, b, c are coefficients of \[x^2 , x \] and constant respectively in the expanded form . .
no they are not coordinates it tells u the nature of the roots whether they are real or imaginary
k I got it so far Do we solve for x?
then use the formula for discriminant as @Avva has suggested to find value of discriminant a=-4, b-24, c= -28
No if the question asks for discriminant you just have to tell the numerical value of \[[b^2 - 4ac] \]
k so if we plug in the numbers -24^2-4(-4)(-28)
exactly thats perfect
and we simplify to get our answer right
@zainulafaq so is it 130 and my work is shown below @zainulafq -24^2-4(-4)(-28) 576+16(-28) 576-448=130
all of it is excellent except for last step . . 576-448 = 128 not 130 . . .
whoops so 128 is my answer
yup now its fine :)
welcome :)
