4x^2 - 9x  - 9  = 0       factor as

 

(4x + 3) (x - 3)   =  0

 

Setting each factor to 0 and solving for x gives that  x  = -3/4   or  x  = 3

 

 

3x^2  + 14x   +  8

 

We can write this as

 

3x^2   +  12x   +  2x  +  8            factor by grouping

 

3x(x + 4)  +  2(x + 4)             take out the GCF  =  x + 4

 

(x + 4) (3x + 2)
