Question

If one of the zeroes of the cubic polynomial ax3+ bx2+ cx+ d is zero, the product of other two zeroes is ​

Answer 1

Answer:

  c/a

Step-by-step explanation:

In general, call the three roots r, s and t.

Then:

• r+s+t = -b/a
• rs + st + tr = c/a
• rst = -d/a

In this question, it is given that r=0.

The second fact above then says:

• st = c/a

Hope that helps.
