Question

if two zeros of polynomial x3+5x2+7x+3 are -1 and -3 then find the third zeroes

Answer 1

Answer: Zeroes of the polynomial are -1, -1, -3.

Step-by-step explanation:

Since -3 and -1 are zeroes of the polynomial, we can write (x+1) and (x+3) as factors of the given polynomial. Dividing it by (x+1)(x+3) we get another factor (x+1). Therefore -1 is the third zero of the polynomial.
