Which of the following are solutions?

The idea is we do some, you learn how to do them, and you do the rest. Last quadratic equation for you. Please ask questions if you're confused.

On this one I'll teach you a shortcut called the Shakespeare Quadratic Formula (2b or -2b):

Let's do our problem.

Shakespeare Quadratic formula time; we have a -8x so b=4:

B C

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
