Question

Verify the relationship between the zeroes and the coefficient of x²+11x+18

Answer 1

Answer:

sum of zeroes = -11

product of zeroes =18

Step-by-step explanation:

x2+11x+18

x2+2x+9x+18

x(x+2)+9(x+2)

(x+9)(x+2)

x+9=0

x=-9

x+2=0

x=-2

sum of zeroes = -9-2

-b/a=-11

a=1,b=-11,c=18

-11/1=-11

=-11

product of zeroes=-9×(-2)

c/a =18/1

=18
