Question

solve the given equation 2 cos^2 θ − cos θ − 1 = 0

Answer 1

factor

Answer 2

yep...factor just as you would a "regular" polynomial of second degree. It works beautifully. If you need help, we can guide you...

Answer 3

Factor it into parenthesis like this: (2 cos theta + )(cos theta - ). Fill in the blanks. Do you know how to do this?

Answer 4

I've got \[2\pi/3+2\pi k\]and \[4\pi/3+2\pi k\] is it correct?

Answer 5

that's for theta
