An acute angle is less than 90 degrees
Answer:
The two roots of the quadratic equation are

Step-by-step explanation:
Original quadratic equation is 
Divide both sides by 9:

Add
to both sides to get rid of the constant on the LHS
==> 
Add
to both sides

This simplifies to

Noting that (a + b)² = a² + 2ab + b²
If we set a = x and b =
we can see that
= 
So

Taking square roots on both sides

So the two roots or solutions of the equation are
and 

So the two roots are

Lets solve this step by step.
8 * 8 = 64
Lets suppose there are 8 aquariums and there are 8 fish in each. Therefore, there are 8 groups of 8 fish. Add and solve.
8+8+8+8+8+8+8+8 = 64
