Question 12

Multiple Choice

Calculate dy dx\frac { \mathrm { d } y } { \mathrm {~d} x } . You need not expand your answer. ? y=(9x2+x) (xx2) y = \left( 9 x ^ { 2 } + x \right) \left( x - x ^ { 2 } \right)


A) (18x+1) (1x) +(xx2) (9x2+x) ( 18 x + 1 ) ( 1 - x ) + \left( x - x ^ { 2 } \right) \left( 9 x ^ { 2 } + x \right)
B) (18x+1) (xx2) +(12x) (9x2x) ( 18 x + 1 ) \left( x - x ^ { 2 } \right) + ( 1 - 2 x ) \left( 9 x ^ { 2 } - x \right)
C) (18x+1) (xx2) +(12x) (9x2+x) ( 18 x + 1 ) \left( x - x ^ { 2 } \right) + ( 1 - 2 x ) \left( 9 x ^ { 2 } + x \right)
D) 36x2+20x+1- 36 x ^ { 2 } + 20 x + 1
E) (18x+1) (1x) +(x2x2) (9x2+x) ( 18 x + 1 ) ( 1 - x ) + \left( x - 2 x ^ { 2 } \right) \left( 9 x ^ { 2 } + x \right)
