The other roots of the given polynomial equation are 2 and -2.
Given polynomial equation is:
[tex]x^{6} -16x^{2} =4x^{4} -64[/tex].....(1)
A polynomial is the sum of monomials of the form axⁿ where n is a whole number.
Rewriting the (1) as:
[tex]x^{6} -4x^{4} -16x^{2} +64=0[/tex]
[tex]x^{4} (x^{2} -4)-16(x^{2} -4)=0[/tex]
[tex](x^{2} -4)(x^{4} -16)=0[/tex]
[tex]x^{2} -4=0[/tex]
[tex]x^{2} =4[/tex]
[tex]x=2[/tex]
[tex]x=-2[/tex]
So, the other roots are 2 and -2.
Hence, the other roots of the given polynomial equation are 2 and -2.
