Question

sum of numbers A and B subtracted from their product ​

Answer 1

Answer:

the sum of numbers = A + B

and product = AB

SO, required polynomial = AB - ( A + B)

Answer 2

$\textrm{Required Answer = Product of 'a' and 'b' - Sum of 'a' and 'b'}$

$\longrightarrow\textrm{Required Answer = (a \times b) - (a + b) = ab - (a + b) = ab - a - b}$
