Find all the zeroes of the equation. 12x 2 - 64 = - x^4

a.) 2, - 2, 4i, - 4i

b.) 2, - 2, 4i, - 4i, 0

c.) 2, 4i

d.) - 2, - 4i

The correct option is answer (a) i. e.

2, - 2, 4i, - 4i

Thr roots of the given equation:

12x^2 - 64 = - x^4 can be founf by putting the given values in the equation and seeing if it satisfies the equation or not.

Example: put 2 in the equation we get, 12*48 - 64 = - 16

Or - 16 = - 16.

Since RHS = LHS.

In similar way, we check all the given roots, if they satisfy the equation or not.
