Answer:

A. Dividing both sides by 4 isolates the variable.

Step-by-step explanation:

In order to solve for x, you need to get it all by itself. Dividing both sides of the equation by 4 gives you 8 on the right side and only x on the left side , therefore the variable is isolated. (This uses the Division Property of Equality.)

Answer:

True

Step-by-step explanation:

That expression is called the "Quadratic formula" and basically the solution to any second degree equation can be find by using the quadratic formula.

Attached you can find the procedure to get to the quadratic formula from the general equation of a second degree polynomial.
