See below in bold.
Step-by-step explanation:
Let the 2 integers be n and n + 2 ( as consecutive odd numbers ascend by 2).
(a). So we have the equation:
n(n + 2) = 323.
(b). n^2 + 2n = 323
n^2 + 2n - 323 = 0
(n + 19 )( n - 17 )
n = `17 ( we ignore the negative).
But 17 * 19 = 323 so
the 2 numbers are 17 and 19.

Hello from MrBillDoesMath!
(x + 6) (2 x - 9)
Discussion:
6 and -9 are the factors of the constant term as 6 * (-9) = -54
The x term is given by -9x + 12x = 3x (multiply the factorization out)
Regards,
MrB
