Question

if two zeroes of polynomial x3+5x2+7x+3 are -1 and -3,then find its third zero
​

Answer 1

Answer:

Step-by-step explanation:

x3 +5x2+7x=3

alpha = -1

bita = -3

gama = ?

alpha + bita + gama = -b/a {coefficient of x2 term/ coefficient of x3 term }

-1 + -3 + ? = 5/1

-4 +? =5

?=5 +4

? = 9

game [ third zero ] = 9

Answer 2
