Answer 1

2 one is

3 and 15...(Ans)

Answer 2

Given : Correction which of the following is not defined if b is non zero integer  

To Find :  Choose correct option :

a)b÷0

b)0÷b

c)b÷1

d)1÷b​

Solution:

 b ÷ 0  is not defined

as we get infinity if we divided by 0

0 ÷b = 0   if b ≠ 0

b ÷ 1 = b

1 ÷ b    is defined if b≠ 0

Hence b ÷ 0  is not defined    if b is non zero integer.

pair of integer in which multiplication is (-45) and difference is 12.​

   x(x - 12) = -45

=> x² - 12x + 45 = 0

no integral solution

if multiplication is 45 and difference is 12 then  15 and 3  and - 15 and - 3

multiplication is (-45) and sum is 12   then 15 and - 3
