For this case we have a factorized quadratic equation. We equal each factor to zero and thus find the roots:

Subtracting 5 from both sides we have:

Thus, the first solution of the equation is:

On the other hand we have:

Adding 3 to both sides:

Thus, the second solution of the equation is:

Answer:
The solutions of the equation are:

Answer:
1.5 rooms
Step-by-step explanation:
1/2 x 3
Answer:
6
Step-by-step explanation:
The correct answers are A C and B
3* (a + 1,5) = - 1,5 [:3
a + 1.5 = - 0,5
a = - 0,5 - 1.5 = -2
