UNIT 1 TEST RETAKE

What is the simplest form when factoring for reals?

The simplest form means no imaginary numbers (i’s) are present.

How do you interpret 'anything else' in factoring?

'Anything else' includes normal factors that may involve irrational numbers.

In synthetic division, what should be noted about the divisor?

Use the opposite sign of the term when dividing; for example, the opposite of 3 is -3.

What does a closed circle indicate when solving quadratic inequalities?

A closed circle indicates that the endpoints are included (greater/less than or equal to).

What does an open circle indicate in quadratic inequalities?

An open circle signifies that the endpoints are not included (greater/less than but not equal to).

What is the first step in solving quadratic inequalities?

Make sure to get one side of the inequality equal to zero.

After getting one side of the inequality equal to zero, what is the next step?

You can factor it out to solve for the zeroes.

When you have a quadratic inequality, what can you do to solve it?

You can factor the inequality after setting one side to zero.

What do you need to check when performing synthetic division?

Ensure you correctly use the opposite of the divisor.

In quadratic inequalities, how do you denote solutions that include endpoints?

Use a closed circle for solutions that include the endpoints.
