Question

find the zeroes of the following quadratic polynomial and verify with their co efficients 1. xsquare-7x+12 2. xsquare-3., 3. 3xsquare-x-4​

Answer 1

Answer:

Given,

x2 +7x+12

zeros

x2 +7x+12=0

(x+3)(x+4)=0

x=−3,−4

verification,

sum of roots =− b

a =−

1

7

=−7

product of roots =

a

c

=

1

12

=12

Hence proved.
