Find the quadratic equation given that the roots are 3 and 9<br>

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 ,

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

The teacher separated her class of twenty-eight student into two group. one group has 4 more than twice as many students as the

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!
