Which option has -4/9 as the zero of a linear polynomial?
Answer and explanation
Correct answer: 9x + 4
Set each candidate polynomial equal to zero to identify its zero. For option C, 9x+4=0 leads to 9x=-4 and hence x=-4/9. Thus option C is correct. Option A has zero 4/9, while options B and D have zero -9/4. The coefficient of x becomes the denominator of the fractional zero after rearranging.
