Solve for the Specified Variable $( b - 7 ) y ^ { 2 } - 11 y + 8 z = 0$

Multiple Choice

Solve for the specified variable. Assume that all other variables are nonzero
- $( b - 7 ) y ^ { 2 } - 11 y + 8 z = 0$ ; for $y$

A) $y = \frac { 11 \pm \sqrt { 121 + 32 b z - 224 z } } { b - 7 }$
B) $y = \frac { 11 \pm \sqrt { 121 - 32 b z + 224 z } } { 2 b - 14 }$
C) $y = \frac { 11 \pm \sqrt { 121 - 32 b z + 224 z } } { b - 7 }$
D) $y = \frac { 11 \pm \sqrt { 121 + 32 b z - 224 z } } { 2 b - 14 }$
