Question

12sec²x-16=0

Solve for the following equation by the quadratic formula..

Answer 1

Explanation:

The equation 12sec²x - 16 = 0 is not a quadratic equation, as it does not have a standard form of ax^2 + bx + c = 0.

To solve for x, we need to isolate sec²x by adding 16 to both sides and then dividing by 12:

12sec²x - 16 + 16 = 0 + 16

12sec²x = 16

sec²x = 16 / 12

sec²x = 4/3

Now that we have isolated sec²x, we can find x by finding the inverse secant of 4/3.

Note that the inverse secant is a multi-valued function, so there may be multiple solutions for x.
