**Question 9:**Two zeros of the polynomial function \( f(x) = x^4 - 7x^3 + x^2 - 63x - 72 \) are \( 3i \) and \( 8 \). In what form are the other roots?**Options:**A. 1 rational, 1 imaginary root B. 1 rational and 1 irrational root C. 2 rational roots D. There are no other roots

Topic = Polynomialf(x)=x4-7x3+x2-63x-72Given zeros are 3i,8if any polynomail having imaginary roots then the roots are in pair . so if one root is 3i then the other root is-3i ⇒x2+9One root is 8 then ⇒x-8f(x)=x4-7x3+x2-63x-72then f(x) can be written in the factored formf(x)=x-8x2+9x+1the roots are x=-1x=-3i
