il63 [147K]

Answer:

\bold\purple{Quadratic \:  \: eq {}^{n} = x {}^{2}  - ( \alpha  +  \beta )x +  \alpha  \beta} \\

Sum of roots ,

( \alpha  +  \beta ) = (3 + 9) = 12

Product of roots ,

( \alpha  \beta ) = (3)(9) = 27

Substituting the values in the above equation ,

\bold{x {}^{2}  - ( \alpha  +  \beta )x +  \alpha  \beta}  \\\\ \bold{⇢ x {}^{2}  - (12)x + 27} \\\\ \bold\blue{ ⇢x {}^{2}  - 12x + 27}

OverLord2011 [107]
You can use a system of equations.
x=group 1
y=group 2

x+y=28
2x+4=y

Isolate the variable in equation 1.

y=-x+28

Substitute it into equation 2.
-x+28=2x+4

Solve.
-3x=-24
x=8

Substitute it into one of the equations for y.
-x+28=y
-8+28=y
y=20

There are 8 students in one group and 20 students in the other.

Hope this helps!
