Factor, Using the Given Factor A) $5 y ^ { 2 } ( 2 y + 1 ) ^ { - 2 / 5 } \left( - 21 y ^ { 2 } - 28 y - 8 \right)$

question 187

Multiple Choice

Factor, using the given factor. Assume all variables represent positive real numbers.
- $15 y ^ { 4 } ( 2 y + 1 ) ^ { - 2 / 5 } + 20 y ^ { 3 } ( 2 y + 1 ) ^ { 3 / 5 } - 40 y ^ { 2 } ( 2 y + 1 ) ^ { 8 / 5 } ; \quad 5 y ^ { 2 } ( 2 y + 1 ) ^ { - 2 / 5 }$

• A) \(5 y ^ { 2 } ( 2 y + 1 ) ^ { - 2 / 5 } \left( - 21 y ^ { 2 } - 28 y - 8 \right)\)
• B) \(5 y ^ { 2 } ( 2 y + 1 ) ^ { - 2 / 5 } \left( 21 y ^ { 2 } - 28 y + 8 \right)\)
• C) \(5 y ^ { 2 } ( 2 y + 1 ) ^ { - 2 / 5 } \left( 19 y ^ { 2 } - 28 y + 8 \right)\)
• D) \(5 y ^ { 2 } ( 2 y + 1 ) ^ { - 2 / 5 } \left( - 19 y ^ { 2 } - 28 y - 8 \right)\)
