To solve a quadratic equation
we can use the quadratic formula:

In your case, the equation is identified by 
So, the solving formula yields

So, the two solutions are derived by choosing the plus sign once, and the minus sign the other time:

can u maybe write the full question?

For this case we have an expression of the form
that was simplified to the expression
. They ask us to indicate which property was used to simplify the expression.
We have that, by definition, the distributive property states that:

So:
is an example of the distributive property.
Answer:
This is an example of the property distributive
Option C
Answer: 24.625
<u>Order the numbers</u>
Before: 17,24,26,13,4,13,20,80
After: 4,13,13,17,20,24,26,80
<u>Add</u>
4+13+13+17+20+24+26+80=197
<u>Divide</u>
197÷8=24.625
V = L * W * H
V = 3 * 5 * 6
V = 90 cubic units
