1.	If two of the zeros of the cubic polynomial `ax^(3)+bx^(2)+cx+d` are 0 then the third zero isA. `(-b)/a`B. `b/a`C. `c/a`D. `(-d)/a`
Answer» Correct Answer - A Let ` alpha, 0, 0` be the zeros of `ax^(3) + bx^(2) + cx + d.` Then, sum of zeros = `(-b)/a rArr alpha+0+0=(-b)/a rArr alpha = (-b)/a.` Hence, the third zeros is `(-b)/a.`
