Answer 2

Answer:

zeroes = -3 and -1

sum of zeroes

= -4

= -b/a

product of zeroes

= 3

= c/a

Step-by-step explanation:

given equation

x² + 4x + 3

here a = 1 , b = 4 , c = 3

x² + 4x + 3 = 0

x² + x + 3x + 3 = 0

x(x + 1) +3(x + 1) = 0

(x +3)(x + 1) = 0

x = -3 , -1

now,

zeroes of the quadratic polynomial

= -3 and - 1

now,

sum of zeroes

= -3 + (-1)

-3 - 1

-4

= -b/a

product of zeroes

= -3(-1)

= 3

= c/a
