Question

Find the zeros of the equation:

Answer 1

\[7x ^{2}-144=-x ^{4}\]

Answer 2

Where are you stuck?

Answer 3

I rewrote the equation so that it has 'x^3' so that it now is in standard form.
\[x ^{4}-0x^{3}+7x ^{2}-144=0 \]
So now I'm wondering if I need to include the '0x^3' in synthetic division to find the remainder
