Solve the equation for all real solutions.

Step-by-step explanation:

You can use the quadratic formula for any quadratic. The quadratic formula is given by , and yields both real and non-real solutions.

In the given equation , we have:

Substituting given values into the quadratic formula, we have:

The attempt in the problem is correct. Sometimes with auto-grading, the solutions need to be in a specific order to be marked correct. I'd suggest submitting the solutions in a different order to check if that's the issue.

to complete this square you have to rotate about the origin 270 degrees clockwise.

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
