Answer:
and 
Step-by-step explanation:
We must solve the quadratic equation to find the values of x that satisfy equality

Subtract 24 on both sides of equality


Now we factor the quadratic equation
Identify two numbers that when you add them you get as a result 2 and when you multiply them you get as a result -24
The numbers sought are: 6 and -4
So the factors are:

Finally note that the solutions are:
and
