A) $9 x ^ { 2 } - 42 x + 45$
B) $9 x ^ { 2 } - 42 x$
C) $9 x ^ { 2 } - 27 x + 45$
D) $9 x ^ { 2 } + 42 x + 45$

The product is found by multiplying each term in the first parenthesis by each term in the second parenthesis: $3x * 3x = 9x^2$, $3x * -9 = -27x$, $-5 * 3x = -15x$, and $-5 * -9 = 45$. Combining like terms ($-27x$ and $-15x$) gives $9x^2 - 42x + 45$.
