please jldi bta do
​

Answer 1

Step-by-step explanation:

ANSWER

Given,

x

2

+7x+12

zeros

x

2

+7x+12=0

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

x=−3,−4

verification,

sum of roots =−

a

b

=−

1

7

=−7

product of roots =

a

c

=

1

12

=12

Hence proved.

Answer 2

Answer:

(ii) (3,4)

Step-by-step explanation:

x2-7x+12=0

x2 -(4x+3x)+12=0

x2 -4x-3x+12=0

x(x-4)-3(x-4)=0

(x-4)(x-3)=0

{x-4=0} {x-3}

{x=4} {x=3}

sum of roots = -b/a

-4-3=-7/1

【-7 = -7】

product of zeroes = c/a

-3×-4 = 12

【12 =12】
