If (x+2) is the HCF of x^{2} + ax + b and x^{2} + cx + d.
Then, (-2)^{2} -2a +b = (-2)^{2} -2c + d
If (x+2) is the HCF of x^{2} + ax + b and x^{2} + cx + d.
Then, (-2)^{2} -2a +b = (-2)^{2} -2c + d
b + 2c = 2a + d

7 / 8 = 0.875,
6 / 7 = 0.857,
4 / 5 = 0.8 and 5/6 = 0.833
Now, 0.875 > 0.857 > 0.833 > 0.8
So, 7/8 is the greatest

L.C.M = ( L.C.M . of 2, 4, 5, 7) / (H.C.F. of 3, 9, 6, 12)
L.C.M = ( L.C.M . of 2, 4, 5, 7) / (H.C.F. of 3, 9, 6, 12)
= 140/3
