Divide the Polynomials by Using an Appropriate Method $$\left( 20 r ^ { 4 } - 28 r ^ { 3 } - 38 r ^ { 2 } + 15 r + 9 \right) \div \left( - 4 r ^ { 2 } + 2 \right)$$

Multiple Choice

Divide the polynomials by using an appropriate method. $$\left( 20 r ^ { 4 } - 28 r ^ { 3 } - 38 r ^ { 2 } + 15 r + 9 \right) \div \left( - 4 r ^ { 2 } + 2 \right)$$

A) $- 5 r ^ { 2 } + 7 r + 7 + \frac { r - 5 } { - 4 r ^ { 2 } + 2 }$
B) $- 5 r ^ { 2 } + 7 r - 7 + \frac { - 6 r - 5 } { - 4 r ^ { 2 } + 2 }$
C) $- 5 r ^ { 2 } + 7 r - 7$
D) $- 5 r ^ { 2 } + 7 r + 7$
