A) $15 x ^ { 2 } - 7 x - 2$
B) $15 x ^ { 2 } - 7 x + 2$
C) $15 x ^ { 2 } + 7 x + 2$
D) $15 x ^ { 2 } + 13 x + 2$
E) $15 x ^ { 2 } - 13 x - 2$

Using the FOIL method: First: $x \cdot 15x = 15x^2$, Outer: $x \cdot (-10) = -10x$, Inner: $\frac{1}{5} \cdot 15x = 3x$, Last: $\frac{1}{5} \cdot (-10) = -2$. Combine like terms: $15x^2 - 10x + 3x - 2 = 15x^2 - 7x - 2$.
