Question 212453
factor,,3x^2 -3x -36 = (3x+9)(x-4) = 3(x+3)(x-4)
.
factor,,3x^2 -15x +12 = (3x-3)(x-4) = 3(x-1)(x-4)
.
LCD = 3(x-4) (x+3)(x-1)
.
restating  problem  over  LCD
.
[(4x+2)(x-1) + (5) (x+3)] / [ 3(x-4)(x+3)(x-1)
.
[ 4x^2 -2x -2 + 5x +15] / { 3(x-4)(x+3)(x-1)]
.
[ 4x^2 +3x +13} / [ 3(x-4)(x+3)(x-1)]
.
This  is  answer,,,if  we  factor  numerator  it  is  a complex  number (x=-.375 +/- 1.763 i )
.
