Answer:

We have

$\frac{x^2-9}{x^2+2x-15}$

$\frac{\left(x+3\right)\left(x-3\right)}{x^2+2x-15}$

$\frac{\left(x+3\right)\left(x-3\right)}{\left(x-3\right)\left(x+5\right)}$

$\frac{x+3}{x+5}$

∴The answer is D

OLEGan [10]

N and m are numbers 3 units apart

n + 3 = m
n = m - 3

Product:

m(m-3) = 108 (ANSWER)
m^2 - 3m - 108 = 0
(m-12)(m+9)=0

m = 12(greates) and -9(void)

n = m - 3
n = 12 - 3
n = 9

therefore the two numbers are 9 and 12
