If x = -1 and x= 2 are the extreme points of y= ` alpha` log x+ `beta` `x^2`+ x then A) `alpha`=6, `beta` = `1/2` B) `alpha`=- 6, `beta` = `- 1/2` C) `alpha`=2, `beta` = `-1/2` D) `alpha`=2, `beta` = `1/2`

A

`alpha`=6, `beta` = 12

B

`alpha`=- 6, `beta` = - 12

C

`alpha`=2, `beta` = -12

D

`alpha`=2, `beta` = 1/2
