A) (32x² + 24x +12) / 16. Notice that the GCD of 32, 24 and 12 is 4
then let's factorize:

4(8x² + 6x + 3) / 16. Now simplify numerator & denominator by 4

Hence a) = (8x² + 6x + 3) / 4

b) 35/(42x² - 49x +21); the GCD (of denominator) of 42, 49 and 21 is 7
then let's factorize:
35/[7(6x² -7x +3); Notice that 35 = 7.5 ; 7.5/ 7(6x²-7x+3)
Now simplify numerator & denominator by 7

Hence b)= 5/(6x²-7x+3)


Now do the same for the others.
