question 169

Multiple Choice

Factor out the greatest common factor. Then determine if the polynomial is a perfect square trinomial. If it is, factor it. $32 r ^ { 2 } - 16 r s + 2 s ^ { 2 }$

• A) \(2 ( 4 r - s ) ( 4 r + s )\)
• B) \(2 ( 4 r - s ) ^ { 2 }\)
• C) \(32 r ^ { 2 } - 16 r s + 2 s ^ { 2 }\); Not a perfect square trinomial
• D) \(2 \left( 16 r ^ { 2 } - 8 r s + s ^ { 2 } \right)\); Not a perfect square trinomial
