Use synthetic division, if you know how, to check the possible root -3. The remainder (if it occurs, if not zero) is the dividend evaluated at x=-3.


-3     |     4     -9     -5     -3     4

With a factor of x + 3, one zero is: - 3
Based on the remainder theorem, remainder is: f(- 3), or %28-+3%29%5E4+-+9%28-+3%29%5E3+-+5%28-+3%29%5E2+-+3%28-+3%29+%2B+4, or highlight_green%28292%29
