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.
